"Hey, uh, not too deep now." "Charlie, I've been opening boxes..." " Yeah, just be careful." " You want to do it?" " Actually, yes, I do want to do it." " You can't, it's my knife." " It's my..." " Charlie's book, the attraction equation." "Oh, yeah?" "So, hitting shelves, huh?" "Yeah, tomorrow night, first book signing." "Ah, nice picture there, bro." "Oh, yeah." "Whoo, look at that." "Where should I sign it?" "Yeah, on the inside." "Title page by the author's name." "Well, shouldn't it just be the first page so I can open it and, boom, I sign it." "No, no." "That-that page is blank." "Not after I sign it." "Well, you look nice." "Out with Liz?" "Uh, I think Larry's right." "You know, it's the title page." "Let's see, um..." ""Charlie Edward Eppes"?" "Or "Charlie Eppes"?" "Or "C. Eppes"?" "I think, you know, depending on attendance, you might want to adjust the length of the signature." "All right, well, then I can use an adaptive algorithm to adjust for variables of time per person." "Uh, so we're talking three hours, probably less than a thousand people, there's probably more than-than..." "I'm going to need a stopwatch." "FBI." " Steven!" " Mom!" "Steven!" "Mom, come on!" "Steven!" "US Marshal Tricia Yaegger." "FBI?" "Yep." "An assassin gained entry to a protected household using an FBI badge." "No signs of forced entry." "She opened the door to her own killer." "Protected?" "Uh, witness protection?" "Witness security." "Leah Wexford was in the program for the last five years." "So was her son, Steven." "And he was shot, too?" "One grazed him, one lodged in his shoulder." "All right, so the killer didn't make sure he was dead." "Oh, the kid hid back there." "Alarm system went off, we had marshals here in under two minutes." "That's fast." "Not fast enough for Leah." "Looks like she was out on a date." "You guys have any idea who she was out with?" "Me." "I was assigned to her case back in Albuquerque." "So that must have been about five years ago?" "RICO cases have a way of never ending." "Organized crime?" "Yeah." "Her husband was a mid-level mobster who was whacked during the investigation." "Leah Wexford knew every person her husband spent time with, every serious player in Albuquerque." "Now, for a RICO case, that makes her the prime witness." "37 years the marshals have been doing witness security." "Never lost a witness." "Really?" "Not one?" "People have been killed after they left the program." "But never one actively under our protection." "Okay, all right, so, what happened here tonight?" "What did happen, Eppes?" "Exposing a witness." "Well, she needed to get out." "Breaking protocol by removing her from the safe perimeter, four times in two months." "Hold on, hold on, you're saying Leah, she couldn't leave her own house?" "Of course she could, but not in the company of a known FBI agent." "As soon as she did that, her risk increased substantially." "You know, I still don't see your point." "Agent Eppes didn't pull the trigger." "But he sure as hell brought that gunman into this house." "It sounds to me like you guys are trying to cover your own ass." "She might be right." " Hey." " Donny." "Everything all right?" "Yeah." "Uh, Charlie up?" "He should be." "We have early classes this morning." "There he is." "Hey." "Hey, what's up?" " Hey, buddy." "Um, just this murder last night like, around 11:00." "I need you to do your radius thing." "An escape radius?" "Yeah." "Wow, after that many hours, calculating the max travel distance will be kind of... just give me something, okay?" "What's up?" "Nothing." "Just-just take a look at the file." "Whatever you can do, I'd appreciate it." "I'm not sure an escape radius is the answer here, but, uh, I'll swing by the FBI and do what I can." "Well, what about your class this morning?" "Oh, I don't have any class this morning." "I just..." "I just like carpooling with you." "All right, so Leah Wexford testified against an Albuquerque mob crew run by Alfred McGurn." "What did they get them on?" "Racketeering, money laundering, black market, prostitution--it goes on." "Yeah, Jake Wexford, Leah's husband, was connected, and they were just about to get him to turn." "And McGurn had him killed?" "Yeah." "The file says that Jake Wexford was a repeat offender." "Why they put someone like that in the program, I..." "Sammy Gravano killed 19 people and they used him to put Gotti away." "If the fish they're after is big enough, they'll put anyone in witness security." "Looks like McGurn's case is coming up on appeal." "Hey, guys." "So, Don asked me to plot an escape radius for the shooter last night that killed a woman, Leah Wexford." "Yeah, she was a witness in a mob case." "Don was her handler." "He never mentioned that to me." "Yeah, he never mentioned it to anyone." "Guys, Leah Wexford was a protected witness." "I mean, Wit." "Security suppressed the information." "That's why Don's beating himself up." "He was the only person outside of Wit." "Sec." "who actually knew where to find her." "So he thinks he led her killer to her?" "That's crazy." "Don would never make that kind of mistake." "Another visitor, Dr. Fleinhardt." "Oh..." "Thank you, Brother." "I don't think Brother Theo likes me very much." "It's not you, it's the world you bring with you." "Are they that way about all visitors?" "That would be the problem." "I'm the only one here who has visitors." "Even the "vow of silence" guys are grumbling." "A woman in the witness protection program was murdered." "My brother... is blaming himself because he feels like he led her killer to her." "And you disagree with Don's conclusion?" "Well, of course." "Meaning that you emotionally disagree." "Well, I mean, if you had facts to support your theory, you'd be talking to Don right now, not me." "What if I perform a classification and regression tree?" "Yeah." "Yeah, CART analysis might well uncover where he went wrong." "If he went wrong." "I don't know..." "I don't know how comfortable I feel performing a CART analysis on my own brother." "Don already thinks he did it." "I mean, truth or doubt-- which will help him sleep?" "So the bitch is dead." "You ever hear of faking remorse?" "I ain't gonna lie to you, one less witness is good for me, right?" "It's pretty good motive." "Maybe to kill Leah Wexford." "What does that mean?" "If you're going to silence somebody, you silence them, you don't shoot their children." "Steven Wexford's a good kid." "Whoever did this, was after straight-up revenge." "And you didn't want revenge?" "A lot of people in jail because of that... because Leah Wexford put them there." "And every one of them has got friends." "Which ones would kill kids?" "Well, none of mine." "Perfect vantage point to watch the house." "That's a lot of butts for someone who just followed Don and Leah back from a restaurant." "Timeline said Don dropped her off at 11:00." "She was killed at 11:10." "You can't smoke this much in ten minutes." "No, but the killer could've waited for Don to bring her home." "Or Don and Leah come home earlier, go inside, and, uh... killer has plenty of time to smoke his pack a day." "You being an agent or a girlfriend right now?" "I tried to access Leah Wexford's file." "And?" "And there are sealed files on Don's involvement with the case." "Sealed by Witness Security?" "No, sealed by the FBI." "Investigation by the Office of Professional Responsibility." "Well, that could be a million things." "Doesn't mean he had an improper relationship." "Old man noticed an SUV with Washington plates parked here for two hours the night of the murder." "Right where you're standing." "Did Town Watch happen to write the plates down?" "No." "But he noticed it was a rental." "A lot of rentals here in LA" "Not so many with parking permits from the Holiday Lodge motel chain." "Did Grandpa hop in and take a ride with our guy, too?" "Guy sits in a rental for a few hours out front of my house..." "I don't know about you, but I'm with Grandpa." "FBI!" "Hey, get the techs in here fast." "He's gone, but he didn't take his car." "Looks like he knew we were coming." "You don't have to stay." "I'm okay." "Yeah, I know." "Did my mom do something?" "Marshal Yaegger said... wait, hold on, she was here?" "She called." "Wanted to know if my mom had seen any old friends, friends from Albuquerque." "And had she?" "Just you." "You're the only person from our old life she ever saw." "It hasn't even sunk in." "I mean, you know, people are treating me differently, but I don't feel any different." "I-I know I should feel something." " Right?" " Don't... worry about how you feel." "She talks about you a lot." "She thinks about you all the time." "Thought." "Not thinks." "Access denied?" "Come here a second." "We ran the fingerprints we found in the motel and look at what we get." "Try it again." "Okay, so are we or are we not matching them against the federal database?" "We're matching them, but they're flagged." "We're being denied access to the owner's file." "The killer is Benny Natale." "Mid-level mobster, worked for McGurn, probably the trigger man in the murder of Leah Wexford's husband five years ago." "Leah's testimony convicted him." "With a rap sheet like this, his prints ought to be all over our system." "We pulled them out five years ago." "We?" "Witness security." "you're telling us that Leah Wexford's killer is in the program, too?" "Five years ago, we busted Benny Natale in New Mexico for numbers running and drug dealing." "I thought you said he killed Jake Wexford." "We could never prove it, but Leah did find evidence against Natale in her husband's safe-- client records." "Enough to put Natale in the hot seat and get him to turn on McGurn's crew." "Mm-hmm, witness security set him up in Seattle same way we set up a house for Leah in LA" "We relocate our witnesses to different cities." "We don't want them running into each other." "All right, it looks like we're back to the whole revenge motive." "Maybe Alfred McGurn was telling me the truth." "Nice to see somebody was on the up-and-up." "What's that supposed to mean?" "Means you knew what Benny Natale was capable of, yet you still protected him." "If I hadn't, we wouldn't have been able to nail McGurn." "Oh, I see, so one scumbag rats out a bigger scumbag and we pay them $60,000 a year for the privilege, move them into a nice house in a new city." "You know how many witnesses we had before wit sec?" "None" "IRS had to take down Al Capone because no one would talk." "Why don't you talk to Steven Wexford, let him know that's why his mom's dead?" "Natale was arrested in Seattle six times after you moved him there, okay?" "There's drugs in here, protection scams, assault." "You gave him a free pass?" "Checks and balances, Agent Granger." "How useful the information is weighed against past and present offenses." "Benny Natale went too far." "You think?" "I just want to know how Natale knew Leah was here." "Another question is:" "Where is he now?" "So you want to talk about it?" "No." "Yeah." "You slept with Leah Wexford and that's why your files are sealed." " What, you looked?" " I tried." "Then your reputation, OPR investigation... it ended in New Mexico, Liz." "I mean, I wasn't even allowed to keep in touch." "Until the appeal came up and then she reached out to you." "She was scared." "And Yaegger was right." "I did, I crossed a line." "Won't argue with that." "Look, I get it, okay?" "She felt safe with you." "Big mistake there." "So that's all it was?" "Just work?" "Okay." "What else do you know about Benny Natale?" "I fought with Yaegger about putting him in Wit Sec." "I tried going over her head." "Not the best way to make friends." "What?" "Natale kills Leah." "He doesn't skip town, he goes back to the hotel?" "Wha-- what's he doing in LA Still?" "So... you think the killer's still here in LA?" "All the evidence points to it." "And yet why would he stay?" "That's what we're trying to figure out." "And that's Benny Natale's witness security file?" "Yeah." "Everything he's been up to in the past five years... and before." " Lawrence" " Charles?" "What do you think about an application of path analysis?" "Model a pattern of behavior?" "Using Natale's rap sheet to extrapolate a predictive analysis of the choices he'll make." "Sort of like a rat in a maze." "We have a set of known variables." "We know the rat wants to escape the maze." "We also know that he has other needs and desires like food, water, and a mate." "Separate from what the rat wants is what the rat doesn't want-- an electric shock, a dead end-- and these are valid parts of the equation known as avoidance goals." "If Natale's staying in LA," "There must be something he desires that outweighs his avoidance goals." "You think you can figure out what he wants so badly?" "We can take a stab at it." "All right, I'll let Don know." " Thanks." " Right." "Well, you certainly do have your work cut out for you." "Classification and regression tree, huh?" "It seems to me you had some misgivings about performing a CART analysis on Don's decisions." "I still do." "And yet... and yet." "If Don's hypothesis is correct and he really is responsible for Leah's death..." "He doesn't have to know about it." "Thank you." "Benny Natale's storied past gave me all the variables" "I needed to put together a triangular path coefficient." "We've got his history in New Mexico, we have his criminal associates, and we have his countless drug busts in both New Mexico and Seattle." "All those variables helped me formulate a path analysis that will help identify his prime motivation for staying in LA." " Drugs." " Probably cocaine." "That fits his M. O., But there are a lot of places to buy cocaine in Los Angeles." "Well, in creating this path coefficient," "I came to one very obvious conclusion-- that history can't change, right?" "Drugs are pretty much the same in New Mexico and Seattle and Los Angeles, but the "people" variable," " that had to change." " Right, because his contacts in New Mexico, they want him killed." "Right, he had to find a new element to work with-- a prominent Seattle-based African-American gang." "All right, because it works in Seattle, it should work in Los Angeles, at least in this guy's mind." "That's exactly it;the probability is that he would employ the same strategy in Los Angeles, and now we know his base of operations is the Holiday Lodge motel." "That helps me to predict his future movements." "All right, so you're saying by figuring out what he was doing, you can make a pretty good guess as to where he's doing it." "All right, so Natale's working around here somewhere and that's a fairly large area, so I can't get more geographically specific without having more precise values for some of the variables." "Oh, yeah, wait, let me see." "Right here, bro, that area." "What, AP47 turf?" "Yeah, that's the AP47 gang." "We'll need the FBI gang task force." "I'll call 'em in." "All right, I'm off to my book signing or else I'm gonna be late." "Wait, wait, I thought that was, uh, tomorrow night." "When was the last time you slept, bro?" "I'm sorry, I can't go." "I didn't expect you to, but it'd be kind of messed up if I didn't show, though, right?" "Yeah." "Okay." "It looks like your killer is working with the AP47 gang." "The mope on the left is Zeke Gibbs, one of their top lieutenants." "This was taken, like, what, 14 hours ago?" "What the hell is going on here, Eppes?" "Hey, this is Chris Frederickson." "He runs the AP47 task force." "Take a look." "See what Natale's up to." "Major drug deal going down tonight." "We've been tracking it for weeks, didn't know the buyer." "Now we do." "I promise you, as soon as he pays for the coke, Natale's all yours." "No, no, no, no, uh-uh." "No way." "Eppes, Eppes, I need this guy." "Man's got a point." "We get a two-fer." "What?" "What is the deal?" "Why do you keep protecting the guy?" "Why are you so close to this?" "Look..." "Eppes, it's your case, it's your choice." "Wait a few hours, we both win." "I get my guy and you get yours." "Come on, think about it." "You are too close." "What, should I just let them run with it?" "What would you do if it were any other case?" "Hi, Charlie." "Oh, good, I thought I was late." "Well.... did no one show up?" "Charlie, the book just came out, there's no publicity." "What do you want?" " I guess, one day, we'll look back at this and laugh." "Right?" " Yeah." "You can tell this story to Oprah." "Professor Eppes." "Can you sign this for me?" "Uh, absolutely." "Well, I hope so." "I mean, uh, I'm kind of an autograph virgin, actually." "My name is allyson with a "Y."" "Okay, allyson with a "Y."" ""Peace, love, and math."" " "Charlie"..." " E-p-p-e-s." "Thank you." "This is my father." "All righty." "Don't read it all in one night." "Okay." "Thank you." "Hey, Charles, if, uh, if you don't mind..." "what are you doing?" "Well, I figure, since we have so muchtime, uh, do you mind?" "Oh, no." "You know what?" "That's very sweet, but you don't have to do that." "Don't have to?" "What do you mean, have to?" "No, you're not up here, and you don't understand." "This is for me." "I'm going to give one to everyone I know." "I mean, it's just... just a book, you know?" "A book?" "Come on!" "It's my son's book." "Okay, wake up." "We have eyes on Natale." "Here comes Gibbs." "Coke should be in the bag." "When they make the sell, we'll take them all." "You all right, man?" "Yeah." "You all right?" "I'm fine." "I'm going to reach in here, and I'll give you some cash." "You can count it." "It's all there." "We good?" "That sack look right to you?" "Looks a little light, doesn't it?" "Yeah, something's hinky." "Go!" "Go!" "Go!" "Shots fired." "Shots fired." "Natale's down." "FBI!" "Freeze!" "Get down!" "Get down!" "Let's go." "Get down on the grndouand turn around!" "I got Gibbs." "Come on." "You have the right to remain silent." "Anything you say..." "I don't think he can hear you, bud." "Natale's dead." "Self-defense." "I feared for my life." "You shot him in cold blood, Zeke." "And I had to." "I got word this dude Natale was planning on smoking my ass, walking away with the product and the money." "Word from who?" "Text message." "No return number." "Give us your phone, we'll check it out, come on." "I ditched it." "Come on, man, I only keep a phone for a week or so, you know?" "It's bad business to have a family plan, you know what I mean?" "Ah, I see, so, you're going to go for this anonymous guardian angel defense, huh?" "Natale was a shooter for the mob." "I take that seriously." "David:" "You know what, zeke?" "It's going to be a hard case to make, especially since we didn't find a gun on Natale." "Say what?" "No, we didn't." "Man, the dude didn't have a gun?" "Then someone set me up." "Guy threw away his phone, threw away his defense, I got a case." "Yeah, well, not till I'm done." "Done with him?" "What are you talking about?" "Natale is over." "You don't even have to take him to trial." "He didn't have a gun." "What if the guy's right?" "I mean, it does smell like a setup." "Guy's a gangbanger." "Saw a chance to roll some guy from Seattle for a pile of cash." "Anyway, ship's sailed." "Zeke Gibbs has cut a deal to roll on the AP47 gang." "Yaegger's doing the paperwork now." "Whoa, you're putting him in Wit Sec?" "Cost of doing business, Eppes." "A small one to shut down AP47." "You know, some historians blame Rasputin for the fall of Tsarist Russia and the rise of communism, and even he didn't get ousted from his monastery." "Oh, are... are they kicking you out of here?" "The calligraphy is on the wall." "Well, if it makes you feel any better," "I brought you a signed copy of my book." "Pretty cool, huh?" "And you know, if any of the monks want a signed copy, you'll let me know?" "I sense you didn't come here for a book signing." "It's my CART analysis." "I can't get an answer." "I thought the killer was..." "dead, and yet, Don is still taking responsibility for that woman's death." "Yeah, but, I mean, now that you know the identity and the goal of the assassin, your CART should be a relatively simple process." "I studied the public data, and I found sealed files on Don." "So whatever decision path he embarked on days ago," "I think the answer may lie in those files from years ago." "You know, we might be able to gain our answer." "By focusing not on what is there, but on what is not there." "All right." "A woman in profile." "Facing another woman, also in profile." "But if we shade in the center... it becomes a vase." "Value shaded reasoning." "If you have all the data except those sealed files, we may well have enough shade to complete your regression tree." "Don:" "Hey, hey," "I'm not done with Gibbs, all right?" "I still got questions about Natale." "It's a drug deal gone bad." "No mystery there." "Oh, what, you in a hurry to protect another one?" "Is that it?" "You still don't get it, Eppes." "What this game is all about-- speed, get them while you can." "Oh, you are quite the cynic, huh?" "I think you slept with Leah for her testimony." "A little sleazy, but it worked." "You don't know what the hell you're talking about." "You bang a lot of agents." "It was only a matter of time before you hit a witness." "You get Gibbs when I'm done with him." "In four hours, I'll have a judge's order for custody." "Four hours, and then Gibbs disappears down Yaegger's rabbit hole." "Just like Natale did five years ago." "Gibbs is a businessman, though." "You don't just go killing customers for no good reason." "Well, that argues that he's telling the truth and someone set him up." "Yeah, these were not unconnected events." "I mean, someone used Natale to kill Leah, and then used Gibbs to kill Natale." "Someone who benefited from Natale's death." "And Leah's." "Look, you know, you don't have to go in there." "I mean, we got plenty of people that can pack up for you." "I have to do it myself." "I have to go home." "Yeah." "I hear you." "My aunt's in there." "It's okay." "Whoa, don't go taking care of me now." "You look like you need it." "I know it gets better." "I think what happens is it gets less." "The weight will always be there." "Forever?" "You know, eventually, you end up hoping so." "Natale shot the Wexford kid." "He got what he deserved." "It just keeps getting better and better for you, huh?" "How grief-struck am I supposed to be?" "Natale ratted me out." "We have two people who can put you in prison." "Now they're both dead." "Agent Sinclair, break it up." "We're prosecuting McGurn, not you." "What the hell are you talking about?" "I'm talking about cooperation." "You don't give it, you don't get it." "Get him out of here." "You've been done with him for five years." "He's important to our case right now." "I don't get to watch the cops fight?" "Tell you what." "When I get Gibbs, you can talk to McGurn again." "So, you think McGurn's responsible for Leah's death?" "Exactly." "I mean, that's the thing, though." "I mean, if you somehow could find a way to connect Gibbs to McGurn, you know, then we're in business." "Yeah, well, let's see," "I can start by applying a multi-application reservoir simulator to compare McGurn's past crimes with what he's most likely to pull next." "What is all this?" "Don, Leah." "That's what's called a classification and regression tree analysis." "CART for short." "What are you doing?" "You're studying me?" "I don't think you led Leah to her death." "I'm trying to prove it." "And, so?" "Yeah, and so," "I began by studying the case, looking at all the connections between all the players, trying to analyze the decisions you made, based on the facts you had at the time." "No, because all decisions start somewhere and grow like a tree." "Choices made, until at the end, they become complex branches of decision making, good or bad." "And then I work backwards, pruning the tree's branches by assigning values to each decision made, then comparing those values, pitting what could've happened against what actually happened." "And I have to tell you, Don, you know, the probability is quite low that any decision you made, any action you took, led her to her death." "So then, what's this here?" "That's the hole that I'm working on right now." "Let me ask you something." "Is there an element to your relationship with her that you've omitted?" "Yeah, Charlie, there is." "Okay." "Okay." "Let me ask you something." "Is there any way you think this thing can connect Gibbs to McGurn?" "Absolutely." "What do you want, Eppes?" "Gibbs is already in our custody." "Yeah, for now." "See, funny thing kept happening when Charlie tried to connect McGurn to the killings." "One name kept popping up." "Yeah." "Yours." "Gibbs mentioned that he met with Natale before, but there's no record of Natale making a previous trip to Los Angeles." "Nothing." "Just happened to be wiped from the file." "Just like you wiped his fingerprints from our database." "I don't know what you're talking about." "How much did McGurn pay you to set this all up?" " You're way off base." " That's not what the facts say." "Here's a fact you're missing." "McGurn had no reason to kill Leah or Natale." "No reason, huh?" "I mean, two witnesses short at his appeal." "Sounds like a pretty smart play to me." "Except there won't be an appeal." "We've spent the last year working on a deal for McGurn to turn against the rest of the Albuquerque mob." "The deal just made." "So you're putting McGurn into witness security now?" "Don't go spreading that around." "It's confidential." "I'm not your enemy." "And McGurn's not your man." "Sorry, I thought we had Yaegger, but it's very difficult to achieve any type of certainty when there are variables being kept secret." "They're just bringing Gibbs to a safe house today." "So I see you finished." " Yeah." " Yeah, well..." "How did I turn out?" "I skirted a few things, but..." "I didn't find any major errors in your judgment." "So what does that mean?" "Don, I became aware of some sealed files at the FBI;" "files on you." "So, you got clearance." "Yeah, but I wouldn't do that." "I was having an affair with her, all right?" "Years ago." "That's what you'd find." "Hearings and reprimands." "You were out with Leah a few days ago?" "Yeah, as a friend." "Period." "Yaegger thinks I was using her." "Well, Yaegger's wrong." "I don't know." "Well, it depends how you look at it, right?" "We got Natale." "We got McGurn." "We're about to take down the whole Albuquerque infrastructure." "All because I slept with her five years ago." "Yeah, well, using your logic," "I could make the case that without your relationship with Leah, her and Steven would've died five years ago." "So all we really know for sure is that Leah made a courageous decision, and you blaming yourself actually lessens her bravery." "What else was in those files?" "Everything." "Was Leah's current address in those files?" "Sure." "What, who else has access to 'em?" "Anyone with the right clearance levels." "Can you use your clearance to get in?" "I mean legally." "I can look at access logs legally." "Yeah." "So... sealed files leave an electronic fingerprint every time they're opened." "If someone accessed your sealed file... check it out." "Someone did access your file." "And used me to get to her." "Hey." "What's the story?" "We're moving Gibbs to the safe house shortly." "All right." "All right, listen." "Yeah." "I want a piece." "Piece of what?" "I know you accessed Eppes' files just days before Leah's murder." "And I know how you found Natale." "You busted him the first time he made a drug deal with Gibbs." "Then you made him snitch for you." "The arrest report falls into the shredder." "Right?" "You think I'd cut a deal with a scumbag like Natale?" "You were the one who told Natale where Leah lived." "You traded Leah's life to get Natale to go into that drug deal as your informant." "Then you set him up to get killed by Gibbs." "A neat line of dominos." "What've you got to keep me quiet?" "Nice try, Eppes!" "I've been winning this game a lot longer than you've been playing it." "Yeah, it was Frederickson." "He was the only one who had access Don and Leah's files." "And he knew her address; he knew where she lived." "Well, we need a confession." "I tried." "Sorry." "There's no way he's getting away with killing Leah." "There's nothing odd in Gibbs' attorney room video." "He didn't say anything we could pick up at least." "And there he is, making his deal with Gibbs, getting his witness." "Are there any other visits?" "Uh, yeah, a few." "Uh, mom, some friends came... girlfriend... whoa, whoa-- hold it right there-- yeah, back up." "Don:" "Let me see that." "Yeah." "Give me a hi-def on that, all right?" "You think he passed her a message?" "Gangs in Pelican Bay have been encoding messages in jailhouse artwork for years." "Sort of like a... like a street steganography." "You know what?" "May I?" "Yeah." "Someone in AP47 has the template to that image." "Overlay it over Gibbs' artwork and all that's left is the hidden message." "Hey, so listen" " I can use a simple morphological image cleaning algorithm to find this hidden message." "It's like a paleontologist working at a dig site." "She knows there's a skeleton underneath all that dirt, but she has to remove all the dirt to find out exactly what the skeleton is." "This morphological algorithm I'm talking about was originally designed to save corrupted images, yet it's proved quite useful in smoothing out gray-scale images, removing the camouflage, revealing the thin features where the hidden message resides." "All right, so how long?" "Might want to get yourself a cup of coffee." "10809, Rubio." "Wait, hold on." "That's the FBI safe house where Gibbs is being held." "He passed it to his gang." "Why?" "His gang is who he's hiding from, right?" "Wait, what if he's been playing Frederickson?" "All right, Gibbs goes along with wit sec, gets himself moved out of high security" "Gets his gang to bust him out, right?" "Don't even think about it." "Expecting someone else?" "All right, get your hands behind your back." "Come on." "Y'all ain't got nothing on me, man." "You can ride home with your boys, go ahead." "What are you doing with my witness?" "I'm arresting him for conspiracy." "To kill you." "Yeah, I know you're the one that set me up." "My brothers know, too." " Come on." " You're dead, homie." "You're just still breathin', that's all!" "Looks like Eppes just saved your life." "I didn't set him up." "He's lying." "So what do you think the life expectancy is of a gang target there, trish?" "Could be days." "I want protection." "I want a confession." "Witness security and I'll deal." "Pelican Bay C-block, that's what you're going to get." "Why are you doing this, man?" "Because you have to ask why." "I needed Gibbs." "He's the key to taking down AP47." "You telling me you don't make compromises, trades..." "Not with people's lives." "Leah was one person." "Take down AP47 and you save hundreds... thousands!" "You pick up a newspaper and read about a gang shooting, it's on you, man." "Can you live with that?" "She was innocent." "Her son's an orphan now." "Can you live with that?" "Well, we had some awfully good luck today." "I mean, Charlie just happened to be there in the exact moment we saw Gibbs' artwork." "Without Charlie, we wouldn't have beaten the gang to the safe house," "Gibbs would be free, and Frederickson would be dead." "Yeah." "So how did Gibbs know about Frederickson?" "'Cause we had Charlie to figure it out." "Who the hell did he have?" "I'll tell you, he couldn't have figured it out on his own." "So I think  someone told Gibbs" "Frederickson set him up." "What do you think, Don?" "Well, what are you asking me this?" "What else don't I know?" "You didn't tell me about Leah until she was dead." "Is that how it's going to be?" "You're not going to give me anything until it blows up on us?" "I can't." "I can't do this." "That's what you always say." "So is that it?" "Yeah, that's .. that's it." "Liz..." "No way you are going back to the monastery?" "No way." "It's period" "Since when did you go on eBay?" "It's a brave new world out there." "Find it oddly exhilirating." "55 dollars!" "What?" "Your book!" " What?" "!" " "Science", Charles Eppes edition." "100$ buyout." "Yeah, there's 4 days left to the bidding." "It could go higher." "Where're you headed?" "To the book store, to get 10 more copies." "Get your pen ready." "Let's do it, pal."
