"Come on." "Let's go, let's go, let's go." "With a score of 2 to 1 in the second period, the Seals have been dominating..." " Donnie." "When did you get here?" " Just now." "Thought I'd watch the end of the game." " Where are you going?" " He's going on a date." " Oh, yeah?" " Yeah." " You know that girl, Donna?" " Yeah." "From Val's wedding, you know, the caterer." "Yeah, her." "Oh, hey, listen." "I wanted to ask you guys something." "It's her birthday coming up and I wanted to get her a gift." "You know, something..." "I don't know." "I just don't know what." "It's just a question of what you wanna say." "Well, how about "Happy birthday"?" "You know, two mathematicians from the University College in London actually recently addressed this very same question." "Mathematicians?" "English mathematicians?" "They used game theory to analyse the best characteristics of a courtship gift." "Yeah, well, no offence, Charlie, sounds like two math geeks who don't date much." "I do take offence." "All right, shut up." "So keep going." "Well, assuming that the goal is the female's receptiveness." " Yes?" " They've found an extravagant gift, one that's costly to the man but of no real financial value to the woman, offers the best chance of success." "So why don't you buy her some flowers?" "You know what?" "Take her to a dinner in a fancy restaurant." "Okay, that's doable." "See?" "You guys still doubt the power of math." "Yeah, well, when it comes to female receptiveness, yes." "Eppes." " Right." "On my way." " What is that?" "Shooting." "Gotta go." "Hey, have fun with..." " Donna." " Right." "Thanks, guys." "I appreciate it." "Hey." "What's going on?" "Looks like a drive-by." "Are you kidding me?" "Why'd they bring us in?" "I just got down here myself." "Cops on the scene were told to sit and wait." " For what?" " For me." "Lieutenant Gary Walker." "L.A.P.D., Gang Impact Team." " Don Eppes, FBI." " Agent Sinclair." "No badges." "U.S. Attorney doesn't want the locals to know FBI's on the scene." "Oh, yeah?" "And why is that?" "Apparently, they don't want anyone to blow his cover." "Though personally, I think it's a little late but I'm not calling the shots." "His name is Anton Rhimes." "We worked an extortion case together down in Long Beach." "Don, he's FBI." "We all use math every day:" "to predict weather, to tell time, to handle money." "Math is more than formulas and equations." "It's logic." "It's rationality." "It's using your mind to solve the biggest mysteries we know." "Agent Rhimes was part of a multi-agency task force." "He'd been working undercover for 10 months." " As a gang member?" " Yeah." "He'd infiltrated the 23rd Street Syndicate and was providing information regarding their leadership." " So they took him out." " That'd be my guess." " Did you find any casings?" " No, but that's not unusual." "They tend to stay in the car in a drive-by." "I'm gonna talk to the U.S. Attorney." "You guys should just keep taking care of the evidence, all right?" "The restaurant was pretty busy all day." "We couldn't pull a single witness." "That's kind of the way it is with these people, agent." "Kind of us versus them out there." "I meant lawmen versus civilians." "Right." "You know what we're waiting on?" "Undercover FBI Agent gets whacked, we all know what happened." "23rd Street bangers found out his identity and had him killed." "In my opinion, we ought to hit them back hard for it." "The longer a thing like this goes unanswered, the more dangerous it gets for all of us out there." "I appreciate your sense of outrage, lieutenant." "Bt we need to confirm that Rhimes' cover was blown" " before we make a move." " This is Robin Brooks." "She's the Assistant U.S. Attorney running the task force" " that Rhimes was on." " I suggest that we grab as many of these 23rd Street bangers as we can for questioning." "Which would be as good as telling them that Rhimes was a federal agent." "But let's not forget, we have a man down." "That means something." "Look, the 23rd Street Syndicate is responsible for dozens of homicides." "Extortion, drug trafficking." "Sorry, I'm not about to blow a 14-month investigation" " to make you feel better." " Let's just take a breath here, okay?" "I mean, an agent did give his life for this case, but there's no point jeopardising what he was working on until we absolutely have to." "Right?" "Let me see what you've got." "Like a lot of gangs, 23rd Street's branching out." "They've set up shop in over nine states." "We've had to turn to federal racketeering provisions to stop them." "You're building a RICO case?" "Same way we've gone after traditional organized crime." "Take down the leadership." "It was Agent Rhimes' job to identify the shot-callers within the 23rd Street Syndicate." "This is a map of local gang territories." "None of the boundaries are exact, as they vary as bordering gangs battle." "They're random and unpredictable." "Actually, they're neither." "Economists have several math models that we can apply to analyse how gangs partition territory." "Now, one of them was actually originally designed to predict plant growth." "In situations of dense population, plants struggle against each other." "They fight to obtain sunlight, to establish dominance." "And it turns out that the same equations designed to predict plant growth, apply themselves remarkably well to borders between rival human populations as well." "What are these flags?" "These are gang-related shootings." "Now, over what time frame?" "How many years?" "Years?" "It's just six months." "Six..." "Six months?" "There's almost a hundred shootings." "Those are only the shootings that are related to the 23rd Street Syndicate." "You want total gang shootings, we're talking more like a thousand." " I'm sorry, in six months?" " Yeah." "Well, I'm assuming the L.A.P.D." "hasn't analyzed this with a regression tree, or run it through a Poisson Clumping analysis?" "Considering I have no idea what that means, I'm gonna say no." "He's a mathematician." "They have their own language." "Charlie, do you see something here?" "There's a lot of information here, and I'm already detecting a pattern." "Now, if I could just get all the files on the shootings," "I might be able to tell you if Agent Rhimes' murder was part of a pattern or an anomaly." "Don, we have the video surveillance from the restaurant." "All right." "All right, that's Rhimes on the right, but who's that?" "That's Travis Watts." "He's high up in the 23rd Street structure." "He's a suspected shot-caller." "Well, looks to me like he took Rhimes out for a last supper, set him up for execution." " I don't know." " What about a warrant sweep?" "You do it all the time." "We could play it low profile, you know." "So we run down 23rd Street members on open warrants, use that leverage to find Watts." "That way, no one knows about Agent Rhimes' cover." "Okay." "Oh, this garage, man." "Do you have any idea how many deadly forms of mould live out here?" "Do you have any idea how many gang-related shootings there were in Los Angeles in the past four years?" "Obviously, I don't have that exact figure," " but something tells me you do." " Take a guess." "Just go ahead." "All shootings, nonfatal and fatal." " Go ahead, take a guess." "How many?" " Okay." "Over the last four years?" "I don't know, let's say a thousand." "Almost 8000." " Really?" " Yeah." "Two thousand of those resulted in deaths." "And most of them occurred 10 or 12 miles from here." "You know, those numbers are overwhelming." "They are." "There's a lot of data here, Larry." "But the police know who the players are." "And if I can just find the key attributes to connect one crime to another," "I can write an algorithm to connect the shootings to the gang members involved." "But Charlie, these issues, they're just so complicated." "And you know, I mean, what you're describing, that seems like a lot to ask, even for Don." "Well, Don did only ask for help with this one case, but don't all these other victims deserve justice?" "Guys." "Game over." "Hey, get back, man." "We'll let you get winners." "No, that ain't gonna work, bro." "We got now." "We need you all to get down on the ground." "Go." "Hit the ground." "Come on." "You know the drill." "I've got him." "Hey." "Get back here." "Hey." "Stop." "Get back here." "Hey, you." "Stop, you!" "Stop right there." "Stop." "Hands up." "Turn around." "Hands up." "Hands on your head." "What the hell is going on?" "I said, what the hell's going on?" "I've got everything under control, okay?" "You've got what under control?" "Ma'am, everything is fine." " I'm just doing my job." " Do you have a warrant?" " Excuse me?" " I'm director of this community centre." "I'm responsible for what happens in this building." "No, I don't have a warrant." "And I don't need one to pursue a suspect." "John, take the kids back in the room." "Come on, guys." "Let's go." "This doesn't have anything to do with us, come on." " Are you all right?" " He ran after me." "I ain't do nothing." "He was told to stop and he ran." "Maybe the gun had something to do with it?" "Kids come here" " to get away from violence." " You need some help?" "Everything's under control, lieutenant." "Ma'am, I have a job to do and you need to let me do it." "Everything's fine." "You see what I'm talking about?" "About the lack of cooperation." "So guess what?" "Anthony here has got not one, but two outstanding warrants." "Isn't that right, Anthony?" "If you say so, man." "Yeah, man, I say so." "Only good news is, today we might give you a chance to change your luck." "How is that?" "We're looking for a friend of yours." "Somebody you might roll with." "Travis Watts." "Anthony, you help us, maybe we worry about these warrants another day." "What's it gonna be, Anthony?" "Where were you the night before last, Travis?" "I don't know, a lot of places." "I get around, you know how it is." "This is you and Anton Rhimes at 6:20." "Only at 6:45, Anton is dead." "Yeah, so I was with him." "But not when he got shot." "I went back for my cell phone." "That's kind of lucky for you." "Why are you asking me all these questions anyway?" "You were there when he was murdered, right?" "And what happened to him will be dealt with." "What's dealt with?" "I'm not saying anything that would incriminate me, but right about now, some shaved heads in Hoover Park are getting a message." "So 23rd Street is retaliating?" "Take one of mine, I'm gonna take five of yours." "If 23rd Street really is retaliating, there's no way they knew Rhimes is FBI." "Just got off the phone with Walker." "A gang unit in Hoover Park just confirmed three separate drive-by shootings." "23rd Street suspected." "So Rhimes' cover was still intact." "But if his cover wasn't blown, why the hell was he killed?" "If Rhimes' cover wasn't blown..." "Then he was just another gang member." "What got him killed then?" "Turf dispute?" "Wrong tattoo?" "Well, 23rd Street retaliated against Hoover Park because they think that they killed Rhimes." "These two gangs have been going at each other hard ever since 23rd Street ripped off a drug shipment from Hoover Park's supplier." "Yeah, but your guys keep track of all gang rivalries, right?" "An enemies list." "Every time a name comes up in a beef with a rival gangbanger, we write it down." "I'd like to take a look at those field reports, see if Rhimes was targeted for being 23rd Street, or it was personal, or..." "Maybe we should look into the personal side." "Maybe he had a concern that he didn't tell the prosecutor but maybe told his wife." "It's definitely worth checking out." "Charlie's here." "He's got something to show you." "Now, what you're seeing is a Behavioral Sequence Analysis." "It's a sequential representation of shootings over the past four years." "What does it give us?" "This kind of dynamic graph is an amazingly good predictor of what I've been calling "shooting chains."" " Shooting chains?" " Shootings that are linked." " One to the next, then to the next." " You mean retaliation shootings." "We already know about all those." "What I'm saying is that it might be possible to follow these shooting chains back to the original shooter." "Without witness and without testimony?" "Visualise a tabletop covered with dominoes." "The first domino to fall is the start of a shooting chain." "Shooting chains can be short." "Shooting chains can be long." "Some shooting chains initiate other branching chains." "Now, we're looking at these shooting chains after the fact... after all the dominoes have fallen." "Reconstructing these chains is going to be difficult." "But there's a way." "By using hierarchical network graphs in combination with Poisson Clumping, we can work our way backwards." "Back to the original dominoes that started the chain." "Which means we can identify the insiders, gang members most prone to violence." " That's correct." " If we remove them from the loop..." "Theoretically we stop future shootings." "You got it." "That's it." "That's an interesting notion." "Interesting?" "Yet you don't seem interested." "Well, it's a matter of priorities." "Eighteen percent of these shootings killed or injured innocent bystanders." "I think some of those people were 10 years old." "Thirty-five percent of the victims were 16 years old or younger." "Yeah, I know." "I'm at those crimes scenes." "And I don't like it." "No matter how many gangbangers we pull in, more are gonna come to take their place." "And frankly, to most people, stopping bad guys from killing bad guys isn't a major priority." "Yeah, again, some of these shootings involved innocent people." " Charlie, Charlie, hey, hey." " That's fine." "Excuse me, that's fine." "You have to forgive me if I feel city-wide gang violence isn't something that one mathematician can stop." "I'm going to have to run, brief the next team." " All right, I'll talk to you later, Gary." " Look." " I'm not here to start trouble." " Listen, listen, all right?" "Let's just concentrate on Rhimes." "You've gotta give the guy a break." "He's been at this for, you know, over 20 years now." "We were planning a family." "It was gonna happen after Anton's undercover assignment was over." "I'm really sorry." "It's funny, you know." "He hasn't been home all that much these last few months, so not having him around, it really hasn't hit me yet." "I was hoping that I could ask you a couple questions." "Sure." "Had your husband mentioned being afraid of anyone or anything in the last couple of weeks?" "Anton afraid?" "He didn't have the gene." "I mean, I'm the one who did the worrying." "So he never mentioned anyone?" "We didn't talk very much lately." "Like I said, he hasn't been around." "I'm in my last year of architecture school and there just never seemed to be enough time." "I understand." "But I can tell he was excited." "You know?" "He'd get that way whenever he's getting close." "I think the people he was after were starting to trust him, starting to let him make decisions." "I can't even give him the funeral he deserves." "Can't even bury him with honour because they still don't wanna blow his cover." "That's quite a job you have." "This is another FBI project judging from the references to firearm violence." "Yeah, well, an FBI agent was killed." "I'm trying to identify possible motives." "By identifying all the links and patterns, is that it?" "So many of these murders are connected that I'm having trouble seeing past the initial relationships." "It's like they're chain reactions." "I'm calling them shooting chains." "You're trying to solve all the shooting chains, is that right?" "Not just one?" " Yeah, maybe." " Oh, Charles, consider Galileo." "Now, he was interested in a single, specific problem:" "Getting a closer look at the planets." "So he built the most powerful telescope of his time." "That's right." "He saw the moons of Jupiter, proving that not everything in the universe revolved around the Earth." "The point, Fleinhardt." "The point." "The point, Mr. Eppes, is that formulating a grand theory is often best done by focusing on a single, small question." "Why did you print out all these photos?" "I don't know." "I was looking at the ages of the victims and I wanted to see their faces." " All right, Daryl." " Bye, Mr. Owens." "All right, David." "Can I give you a hand there?" "Thanks." "You're the one who was chasing that kid earlier." "That's right." "Who are you after now?" "I'm not after anyone." "Don't get me wrong." "Those that run need chasing." "It's the kids I worry about." "They can still be saved." "John Owens." " David Sinclair." " Nice to meet you." " The lady I was talking to earlier?" " Olivia?" " She still around?" " Olivia's always around." "She's probably inside." "Thanks." "Hope you didn't come by to make more trouble." "No, I just wanted to ask you a few questions, that's all." "About Anthony?" "No, we cut Anthony loose." "Turns out he really didn't do anything." "At least you admit when you make a mistake." "There was a murder down here the other night." "Been a bunch of murders down here." "This one had a few witnesses though." "I thought maybe you could help me get someone to come forward." "Give us some help." "Help you?" "Wait a minute." "Just hold on for a second." "You have a problem with trying to solve a murder?" "People get shot around here every day." "Never much effort finding witnesses." "It just makes me wonder, why all the interest now?" "Who was it that got shot?" "Look, whatever you think about me, okay, about the police, people around here seem to listen to you." "And I am asking for your help." "You mean you're asking me to trust you." "Yeah, I guess I am." "And I'm supposed to do that because you have a badge?" "I'm sorry, you haven't been down here enough for me to trust you." "A man lost his life." "I'm not here to restore your faith in the system." "I am just trying to find his killer." "If you think you want to help with that, call me." "Donnie." " Dad." " What's going on?" "Not much." "Things are just not coming together on this one." "Yeah, I know." "I saw some of what Charlie's been working on." "Charlie." "He's looking at every gang shooting for the last four years, which is a lot." "Well, he follows the numbers." "The more something seems unsolvable, the more he wants to solve it." "Well, he's wasting time." "He's looking at way too much." "Look, I don't think he expects to solve something that's been going on that long." "With decades of bad urban planning, and racism and economic blight, gang violence doesn't go away overnight." "It's just that it's Charlie." "He has to get to understand the entire picture." "Hey." "Don." "Hey." "I got news for you." " Rhimes or the 4000 other shootings?" " Both." "I was able to discover a pattern." "Nine shootings, all of them connected, right?" "With Agent Rhimes, you've got 10." "Connected?" "As in all part of the same chain?" "No." "Each one of the 10 is the start of its own shooting chain." "And I think they're all the work of the same killer." "So you're saying that Rhimes' killer is responsible for 10 murders?" "No, far more." "I mean, he may have pulled the trigger on those 10 murders." "They aren't his only victims." "Right, because of all the retaliation shootings." "Right." "When you include all the victims from these 10 shooting chains, you've got yourself one person setting off over 60 murders." "Hey, guys, listen up." "I got nine separate gang shootings over the last two years." "Charlie thinks that they're all related to Rhimes' murder." " Related how?" " All the same shooter." " The same shooter?" " That's right." "Ten kills?" "I don't care how hard-core a gangbanger we're talking about." "This guy would be a legend." "He's right." "Plus, the shootings are spread throughout completely different gang territories, exploiting different rivalries." "If Charlie's math says they're connected, the odds are they are connected." "I have three files here." "All victims are different races." "Plus, they all have a different weapon." "A.25 cal." "What's this, .44, that's a nine millimetre." "Yeah, same here." "They're all different." "That's why we need to look at this stuff." "Run the prints, the ballistics, anything we can, okay?" "Hold on a second." " You see something?" " All three of these, four if you count Rhimes, are single homicides." " The victim is isolated." " Yeah, this one is too." " What about these?" " Same." " Yeah, here too." " Yeah, this one as well." "So?" "So that doesn't happen by accident." "It might just be about opportunity, or it might be part of a bigger plan." "But either way, it supports Charlie's theory." "That there's a single killer with a specific method of finding his victims." "All right, let's check into this, let's go." " Professor Fleinhardt." " Oh, Agent Reeves." " Hi, Amita." " Hi." " Charlie." " Hey." "Wow." "You have a lot of victim photos." "A lot of victims." "Don told me your theory." "Assuming that you're right," "I'm trying to figure out how the killer is finding his victims." "And I don't have a behavioural model yet, but it seems that it has to be more than opportunity." "And I can tell you mathematically, yeah, it has to be." "What does that mean?" "Why?" "Each of these murders started an exceptionally long shooting chain." "Now, the average for a shooting chain is about 2.8 shootings." "These are all much higher." "Look." "Four, five, six, seven shootings even." "Statistically, that wouldn't happen if he'd chosen the victims at random." "Chains would confirm to the overall average." "So there is a method to how he is choosing his victims." "In other words, the killer's choosing his victims specifically to maximise retaliation." "So he's trying to take out as many gang members as possible." "But wouldn't that also endanger members of his own gang?" "I mean, surely they're gonna be the target of the retaliation." "But you see, now you're making this rather large assumption." "I mean, how do we know that the shooter is a gang member?" "A serial killer?" "Targeting gang members for the same reason other serial killers target prostitutes." "Somebody really cares about the victims." "Exactly." "And then they can go on killing for longer without anyone noticing." "I mean, this guy's been out there for like, two years." "If he hadn't killed Rhimes, we wouldn't know who he is." "Charlie says if he's been maximizing retaliations." "He'd have to know a lot about gangs." "I mean, about their structure, how they function." "Right." "That's how he knows who to go after." "All right, yeah, I've got you." "It's ballistics." "One of the slugs we've been testing hit on the computer." "Turns out the same gun was used in a liquor store robbery-homicide." "Let's run down the guy who owns the gun, to find our shooter." "Problem is, this gun's not even supposed to exist anymore." " What does that mean?" " Turned in to one of those buy-back programmes." "You know, turn in your gun, get a free gift at Christmastime." " Those guns were destroyed?" " They're supposed to be." "But obviously this one wasn't." " You got this?" "Thank you." " Got it." "Ready, homes?" "Could you do that for me?" "Yo, the car." "This is part of the shooting chain related to Anton Rhimes' murder." "23rd Street retaliated against Hoover Park this afternoon." "Tonight, Hoover Park strikes back." " It's probably not over either." " No." "Oh, man, that's Anthony, huh?" "Yeah." "Been better off if you'd locked him up." "Hey, David, let me talk to you for a second." "I did some checking into that gun." "The one missing from the buy-back programme." "Yeah?" "I dug up some paperwork, and take a look at this." "Signature on the bottom of that receipt." "Lieutenant Gary Walker." "Yeah." "Could be completely innocent, but at some point or another, the gun that killed Rhimes passed through Walker's hands." "I don't think I like what you're suggesting." "It's not a question, because your name is on the form, right?" "That's your name." "It's not a forgery." "The investigation brings us to you." "I'm sorry." "My name's on about a thousand forms." "I've been working the buy-back programme in my division for six years." "Collecting weapons that were supposed to be melted down." "You know how many guns we take in off the street?" "How many lives we save because of it?" "Why don't you tell me how a gun you signed for ends back on the street in the hands of a killer?" "Who the hell knows?" "Security's not perfect at these things, a lot of people come through here." "Now, we probably took 50 guns off the street that day." "If one of them slipped though, got back out, that's still 49 others we took in." "They're not in the hands of a murderer." "Come on, Eppes." "We're talking about a motivated individual out there, killing." "If it hadn't been this gun, it would've been another one, you and I know that." " All right." " Don, excuse me." "The guys upstairs ran a full audit." "More than a dozen guns from the buy-back programme never made it to the furnace." "Okay then, just tell me how the programme works." "What is the exact chain of possession?" "There's usually maybe five or six drop-off locations." " Churches, community centres." " Community centres?" "Is there any way to check each weapon against the location it was turned in to?" "Well, just by the responsible police officer's signatures." "And turns out all these guns were signed for by you, lieutenant." "Which means they were all turned in at the same location." "Right." "Which is the 23rd Street community centre." "You do see the obscene irony here, don't you, Agent Sinclair?" "We're one of the places that's trying to do some good and you're coming down on us." "Ms. Rawlings, I'm not coming down on you." "The gun buy-back is a good programme." "That may be, but we need to see those records." "We need to know everyone who was working here the day the guns were collected." "These are people who help, people who contribute." "Do you have any idea how hard it is to get volunteers if they can't lend a hand without getting a visit from the FBI?" "Ms. Rawlings, I want names and addresses." "Anyone who had access to those guns." " I know you do background checks." " What if I won't give them to you?" "We can get a court order and make this public." "And I suppose the community centre could find itself liable for the victims' families, if it came to that." "I hope you're really proud of yourself." "You're doing a whole lot to give back to this community." "Ten people had the opportunity to get their hands on the guns that were turned in at the 23rd Street community centre." " Those are the background checks." " We can rule out the priest, huh?" "These six strike me as possibilities." "They can have the necessary gang knowledge and the ability to pull something like this off." "We just need to find a way to connect them to the victims." "Specifically, the first victim." "Because with serial killers, the first victim almost always has significance." "It's the first kill." "It's a really big step." "It means it's personal, or someone close, accessible." "So victim number one is where we're looking to find our link." "It's Omar Brice." "He was shot outside of a party two years ago." "All right, I'll take the family." "You want to pull his record, talk to his PO?" "I'll see what Walker's gang unit has on him." "Has to be a link between him and one of our suspects." "Hey." "Are you still working?" "Yeah, I just needed a break." " Where's Dad?" " He's upstairs." "He just got home from his date with Donna." "Oh, yeah?" "So how'd it go?" "Fine." "The date went fine." "Yeah?" "What'd you end up getting her?" "According to London mathematicians, you should've sprung for expensive dinner." "I disagree." "I think women want something that'll last." "Something to remember the night by, at least." "That would be ideal." "I'm afraid to ask." "What did you get her?" " Soap." " Soap?" " Very expensive soap." " Yeah?" "How'd that go over?" "Well..." "Honestly speaking, she wasn't wowed." "I mean, she was very polite about it, but she wasn't wowed." " Ruined the whole date, didn't it?" "It didn't ruin the date." "Date was fine." "You're home at 9:30." "I didn't say it couldn't have been better." "You look exhausted, you know that?" "I'm just killing myself to find a link between our suspects and this first victim." "Well, at least you have suspects." "Hey, Don, why are you looking to link your suspects to the first victim?" "When it comes to murderers, there's always significance to the first victim." "Well, I understand that." "But what I mean is, why aren't you looking at the whole first chain?" "What do you mean?" "Now, remember I compared the shooting chains to dominoes?" "All right?" "Okay." "So let's say I'm the killer." "And I have reason to want this gang member killed." "We'll call him Bob." "Now, I can just shoot Bob myself." "The smarter move." "Assuming I know the gang's structure well enough." "Instead of shooting Bob," "I shoot Tim, knowing that shooting Tim would set off a chain that ultimately results in the shooting of my real target, Bob." "That is smart." "You're never involved in the shooting of Bob." "Since you don't have a motive for killing Tim, you're not a suspect there, either." "Check the whole first chain." "Your target's going to be in there." "Yeah." "Good, Charlie." "All right." "Thanks." " What are we working on?" " First shooting chain." "We only looked at the first link, Omar Brice." "What if Brice wasn't the real target?" "What if the real target was someone further down the chain?" "That makes sense." "At the time of Brice's murder, LAPD focused on three suspects, they're all Hoover Park gang members, they all made threats against Brice." "Carlos Alvarez," "Jesse Orosco and Peter Mendez." "I have the murder file on Orosco, Jesse right here." "He was gunned down one week after the Brice slaying." "So Orosco was victim number two in the shooting chain." "Yeah." "Wait a minute." "Where's the file on the community centre volunteers?" "It's right over here." " Why, what have you got?" " Orosco, at the time of his murder, he was a suspect in another drive-by, one that killed a 15-year-old kid named Brian Owens." "Kid's father, John, works at the community centre." "Really?" "He was present at all the gun buy-backs." "So this guy's son gets shot in the drive-by." "He starts a chain that ends up killing the gangbanger that's responsible." "Only the killing didn't stop there." "Spotter says Owens is inside, alone." "I tried calling but he's not picking up." "The dude's armed for sure." "I talked to one of his neighbours." "Says he sees him out on his porch at night with a rifle." "Pretty sure it's an AK." "Yeah, plus the guns he got from the buy-back programme." "What we need is to lure him near a window, give my snipers a clean shot." "Shoot first, ask questions later, right?" "Lives are in danger, Agent Sinclair." "Lives of the people who live here." "Don, I met this guy." "Let me see if I can talk to him." "Just give me a shot." "Maybe it doesn't end with a sniper's bullet." "All right." "John Owens, can you hear me?" "This is Agent Sinclair." "I helped you with the tables the other day at the community centre." "You remember?" " Hold." "Hold." " Hold." "Calm down, John." "Calm down." "Easy." "Lower that rifle." " Get our man in position." " Right." "I got nothing to say to you, Sinclair." "Okay." "Maybe you can just listen." "I know about your son." "I know what happened to him." "He was 15 years old." "Fifteen." "Only I couldn't protect him." "I know." "John, this should have never happened." "But what you're doing, more people are going to get hurt." "It's too late for all that." "What about the kids?" "Remember the ones you said could still be saved?" "What about them, John?" "They still need you." "I'm going to jail." "We both know that." "John, listen to me." "Now, you put that gun down and you come on out here." "Nobody else has to get hurt today, okay?" "John?" "Hey, John." "Talk to me." "John, keep talking to me, man." "I'm right here." "John." "Hey, John." " John, talk to me." " David." " Come back out here, John." " Get down." "Come back to the window." " Shots fired!" " Stand by." "Shots fired." "Roll call." "Roll call." "You okay?" "He shot himself." "I heard." "How's David?" "I sent him home." "Colby's with him." "Your man, Sinclair, did himself proud today." "He's got nothing to feel bad about." "We all went home safe." "And that's about as much as you can ask." "I was gonna go see Rhimes' wife and tell her what happened." "I'll see you tomorrow." " Hello." " Yeah, we're coming down." "Yeah?" "Where are you going?" " Out." " He's got yet another date." "Oh, yeah?" "With what's her name, Donna?" "I thought that wasn't going to work out." "Well, your brother came to my rescue." "I bought gift number two on that courtship study list, theatre tickets." "According to the mathematicians, the British ones, this is a sure thing." "Well, maybe not a sure thing, but it's certainly better than, you know, soap." " I don't need math to figure that out." " Thanks for your insights, Don Juan." "So what are you up to tonight, Donnie?" "I thought I was gonna hang with you boys but..." "Man, I wished you'd called." "I'm going to Amita's for dinner." "Larry's gonna be there." "Why don't you join us?" "No, I think I'll just grab something to eat here and head home." " All right." "You sure?" " Yeah, go ahead, have fun." "I got stuff to do anyway." " Have a good time." " Okay, all right." "Say someone steps right up to you?" "All up in you?" "What are you gonna do?" "I know what you wanna do." "What are you gonna do?" "First thing you're gonna do is think." "I'm trying to get you guys to see there are other ways to keep your respect than just resorting to violence." "You've got more options than that." "All right, y'all give me a second?" "Hey, how you doing?" "My assistant told me someone was gonna take over for John tonight." "Didn't expect it was gonna be you." "Yeah, it was conflict resolution." "Class like that would've really helped me out when I was a kid, so..." "Oh, yeah?" "Yeah." "I was a bit of a hard ass." "Was?" "You really do like to fight." "Maybe you want to sit in?" "You can learn some good ways to work things out." "And I won't even call on you." "I'll let you sit there and just watch me." "If you want to." "Let them know when you're done so they can turn out the lights when you leave." "Yes, ma'am." "And I assume, an FBI agent like you can figure out how to find my number." "What you all looking at?" "All right." "Where were we?" "We were talking about options." "Options to violence." "Right?" "Say you get to the bus stop in line, somebody steps, boom, right on your sneakers." "What are you gonna do?"
