"OK, who's got the target?" "It's me." "I'm on him." "I'm heading south on Figueroa." "Now David, I want you to take the next right." "You hopscotch *** pick up trail, right?" "Copy that." "Hi." "Subject's pulled over on 7th." "He's getting out of it." "Colby." " David." "Gotta tag to him." "I got him." "Just carrying a gym bag." "Headed east." "That puts them heading toward you, David." "Just crossed over to the South 7th Street." "Almost at 7th. *** a visual any second now." "Damn, that was close." "David, he make you?" "No, don't think so." "Just tell them to stay back, because if * realizes that we're onto him, * the whole structure of this territory changes." "Charlie, they know what they're doing." "I spent days on this, working with what little we have." "So please." "Guys, keep your distance, all right?" "Yeah, I got you." "Just turned into one of the produce warehouses." "Copy that." "I'll circle around back." "I don't see him." "Don, we've lost visual." "This guy's the only link." "The only link we have to the rest of these terrorists." " Charlie, I know that." "David, you got him?" "I just picked him up." "He's at the north end, heading for the cold storage." "He still has the gym bag with him." "Why don't you watch where the hell you're going?" " Watch where I'm going?" "You walked right into me!" "What are you, an idiot?" "I'm pushing a truckload of vegetables." "How hard is it to see me coming?" "Don, we might have a problem." "This is getting out of hand." "Hold your position." "Just hold your position." "Freeze!" "Drop that crowbar." "Put it down." "Put it down!" "This is a lot of cash, huh?" "Where were you going with all this?" "Look, we know it was gonna be used to pay for a terrorist attack here in L.A." "We know where the money came from; we know you're a part of a terrorist cell that was operating locally." "You keep using that word, "terrorist."" "I'm a soldier, fighting a war America initiated." "Your war against Islam." "Come on, man." "You're from Fullerton-- your name is Timothy." "Kaleed Asan... is my name now." " I want to know about that attack." "What are you gonna tell me about that attack?" "Only that it's God's will... and you can't stop it." "We get anything out of him?" "Don, I had no choice." "I had to take him." " Yeah, I told you to hold." "He was gonna kill that guy." " Right, David, the question is, how many thousands of lives did we trade for that one." "So you think the attack is real?" "Oh, yeah." "Let me talk to him." " I doubt you're gonna learn anything from him." " I don't know about that, Charlie-- I'm feeling pretty persuasive right now, okay?" "No." "He doesn't even know enough to help us." "The structure of a terror cell is what we call a "distributed autonomous network."" "It's made up of a number of independent parts working collectively, but there's no lateral communication." "Think of those huge signs at a baseball game, where everyone in a particular section is asked to raise a card above their head." "Now, the designer of the sign uses a blueprint to place the cards under the individual seats." "The fans don't need to know what the message is." "They just need to know what their particular job is;" "in this case, raising the card." "So once the message is formed, the mission is complete." "And it's the same thing with the structure of a terror cell." "Individual players only need to know their parts, nothing else." " All right, Charlie, what about using more math-- you know, filling in more of the network diagram?" " You know what?" "Frankly, I don't even know if this much is correct anymore." "A terror cell structure is dynamic, and now that they know that we're on to them, the structure of their entire organization is likely to change." "That's great." "Capture:" "FRM@MAOREN Sync:knlight" "Okay, Listen up." "We're racing the clock here." "For those of you from visiting agencies," "I'm Assistant Director Wright." "Agent Eppes has been handling this since it broke, so I'm just gonna hand off directly to him." "Agent." "Ten days ago," "CIA operatives in Yemen found a laptop." "It had information about the funding of a terrorist attack here, in L.A." "Now, Charlie," "Professor Charles Eppes, came up with an algorithm that identified this man as the guy who's going to get that funding." "Now, he also identified two other possible conspirators." "Now, we think they're low-level, part of a homegrown cell operating here in L.A." "American-born, but definitely did time in those Afghani training camps." "Hopefully, Charlie will keep making progress on his angle and we just got to get going on ours." "Okay, the threat is real." "The NSA is reporting an increase in terrorist chatter." "We've intercepted funding and apprehended an active participant in the plot, so we need to do anything and everything within our power to figure out what we're up against and stop it." "Captain Adams, Army CID." "How you doing?" "Do you know Charlie?" "I may have some information about your suspect." "What" " Asan?" "Yeah." "You're aware of his time spent in the Army?" "Yeah, that's where he converted to Islam, right?" "There was another soldier there:" "Michael Rains." "He's since taken the name Ali al Dossari." "Uh, that's not a name I came across." "Well, they were in the same unit." "In fact, it was al Dossari who convinced Asan to convert." "They were given general discharges around the same time." " Wow." "This guy may be the level two connection" "I'm looking for." "You get an address?" "No, my information ends at the time he was discharged." "Okay, but, Captain, any background you may have will help you with my work, so..." "I've got a duplicate file." "That's terrific, thank you." "By the way, Professor, novel approach-- you trying to map out the group's structure mathematically." "I wouldn't call it novel." "Distributed Autonomous Networks are a well-accepted field of study." "If you say so." "I've been in antiterrorism for ten years." "I haven't found a substitute for basic information gathering." "Well, information's only as good as what you can do with it." "Okay, got an address on al Dossari." "Any reason we shouldn't go right at this guy?" "Cell structure's already disrupted." "They know we're on to them." "All right-- hey, guys!" "We're gonna bring this guy in." "You want to fill them in on the way?" "Absolutly." "Ali al Dossari." "FBI." "It looks clear." "Yeah, he's not here." "Take a look at this." "He was forging Marine ID's." "Maybe they're going to try to sneak on to a military base." "Could be the next target." "Yeah, or maybe he was after munitions." "Tons of explosives available on a base if you can get to it." "Sergeant Surplus-- a military surplus store." "I'll alert the local bases, have them double up on security." "If we're not already too late." "These guys are way ahead of us." "Oh, there you are, Charlie." "What's all this now?" "I'm, uh, using connections between weighted vertices to, uh... to find a way to link this man to the times, dates, places and people that we've already associated with the terror cell." "I see." "Having any luck?" "I am, actually." "If I'm correct... he belongs... right... here." "Is that sort of a breakthrough?" "Yeah, the only downside is I didn't find him on my own." "Since when has sharing credit been a problem for you." "Since I'm sharing it with an army captain that was more than a little patronizing about my work." "Pretty scary, isn't it?" "I mean the fact that there might be a terrorist attack in Los Angeles." "Well, a terrorist attack just about anywhere is scary." "No, you know what I mean." "I mean the city is so enormous." "A lot of, uh..." "vulnerable targets." "Hey, I was just about to call you." "Dossari is definitely connected to this." "Yeah, that's what I was gonna tell you." "Adams beat you to it." "I mean they found evidence in Dossari's apartment linking him to Asan." "So, I just wanted to let you know, okay." "I'll check in with you later." "Hey." " So, the clerk at the surplus store" "ID'd al Dossari's picture." "Said he came in and bought two sets of Marine fatigues." "Full deal, boots to caps." "Fake ID's, uniforms-- what, these guys can basically walk onto any base." "Just got a report from LAPD." "There was a theft last night;" "chemical supply company out in Alhambra." "Security guard was killed in the process." "Place called RNE Chemical Supply." "Is it relevant?" "It sounds like a civilian facility." "Yeah, it is." "But the two guys who hit the place-- dressed as Marines." "The owner says the company does a lot of business with local military bases, mostly supply and cleaning chemicals and a few medical supplies." "As a result, a lot of soldiers do pickups." "Gate guard saw the uniforms, the badge, he opened the gate." "We get anything on this truck?" "Vehicle was stolen from a company that provides vehicles to movie studios." "It was a prop." " Yeah." "They don't have video cameras in the chemical storage area these guys got into, but you can see them coming out right about here." "Guard started to question their paperwork or, um... they didn't have any." "Whole thing took less than six minutes." "They knew exactly what they were after." "Chemical called MPDC." "It stands for methylphosphonyl dichloride." "Is that an explosive?" " It's a lot worse than that." "It's the major component in the deadly poison" "Sarin." "But it's only a component." "Yeah, it has to be mixed with several other chemicals, most of them common, but, um, it's one that's kind of hard to get your hands on-- trimethyl... phosphor-something" "Will you run a check on that?" "I did-- turns out three weeks ago, 60 gallons of it went missing from a train yard in Colton." "Oh, my God." "They got everything they need to make sarin." "Yeah, enough of it to poison half the city." "Sarin-- you picked one of my favorites." "I'm sorry-- your favorites?" "Professor Osaki's an organic chemist with a different appreciation than you or me." "Admittedly." "You see, sarin is an efficient, elegantly-structured molecule that does precisely what it was designed to do." "Yeah, what's that?" "Kill." "It's a nerve agent, an extremely volatile one, to boot." "It evaporates quickly." "It becomes a vapor." "So people breathe it, they're affected." "If they breathe it or ingest it, or if comes into contact with their skin or eyes..." "So what do we look for?" "What are the warning signs?" "Wouldn't be as effective if there were warning signs." "There's no odor, taste or color." "For the most part, the sudden symptoms are the only indication of exposure." "All right, so let me ask you this:" "if you had the components, how difficult is it to manufacture?" "It definitely requires some skill, but most of the grad students here could do it." "And an important aspect of that" "Sarin has a short shelf life-- a few days-- so it's usually kept in its binary components." "Meaning, once it's mixed..." "Once it's mixed, it's time to use it." "Hey, Dad, the population density studies, the maps, the stuff from when you were a city planner, all the traffic flow diagrams, where is all that stuff?" "I left it in the garage..." " Oh, I keep it, uh, handy." "You took it?" "Yeah, it's right here." " Oh, okay." "Ever since you've been working with your brother, this stuff has had almost as much use as when I was working." " Thank you." "So what's happened?" "You come up with some other breakthrough?" "Yeah, the attack we're worried about, it could be sarin." "Sarin?" "Wow." "Yeah, the FBI's putting together a list of potential targets." "I'm going to use a threat analysis to see if I can determine which is the most likely target." "Well, if it's a gas attack, they'd have to through some enclosed venue, wouldn't they?" "I mean, like the subway or, um, shopping malls." "Yeah, maybe." "The thing is, these guys potentially have a lot of sarin, they don't have a lot of operatives." " So the question is, how can a couple of guys distribute a lot of sarin?" "Exactly." "So, assuming they want a high casualty count with a more pinpointed application of sarin..." "Maybe I can mark off some possible targets on this map." "Maybe I could come up with something." "County Health sent an alert to area hospitals advising to stock up on sarin antidote, right?" "Yeah, let's hope they don't need to use it." "That's just it, they already have." "The emergency room at Good Samaritan admitted two patients about an hour ago-- both confirmed cases of sarin poisoning." "All right, but there's only two?" "What, two's not enough for you?" " Think about it: if this was an attack, it'd probably be more than two victims, right?" " It means these two probably aren't victims, they're either mixing the chemicals or transporting them." "They're part of the plan." "FBI, Agent Granger." "Agent Sinclair." "You guys awake?" "Can you hear me?" "These guys are too far gone." "I'll find someone." "What's going on in here?" "You stay away from him." "We're federal agents." "We're conducting a terrorism investigation, ma'am." "You think my husband and son are terrorists?" "They were poisoned." "Someone did this to them." "How?" "I mean, where do you think they might've come into contact with sarin?" "I don't know." "They haven't been out of my sight." "We were moving into our first house." "Our very own." "You were moving?" "We were packing." "My husband and son were carrying boxes, loading them into the truck." "I went outside to help them and I found my husband collapsed." "I thought it was a heart attack." "And then I saw my son, too." "Whose truck were they loading, ma'am?" "I don't know." "I mean, it's a rental." "My husband got it last night." "David, man, what do you think of Warner?" "What do you mean, what do I think?" "You know, we've been teamed up a couple of times." "Seems like we have a pretty good vibe going, you know?" "Granger, don't-- seriously." "Why not, man?" "Warner and Don, that's why not." "There is something definitely going on there." " Really?" "Don...?" "What?" "What's going on?" "Nothing." "The Hazmat guys are ready to go." "It's hot." "That's a positive hit on sarin." "It's safe." "Spill was localized to a small spot in the cargo area." "It's been neutralized." " Do we know who rented it?" "The guy used a fake name and a fake ID" "We have a composite artist working on a photo." "Meantime, we're pulling prints off the truck." "Pulled almost a hundred so far." "Hey, Don." "What's going on?" "What are you guys doing here?" "We finished modeling the different attack scenarios." "I think we got their target nailed down;" "it's very ingenious." "Take a look." "What are you talking about "we"?" "It's the water supply." "Probability of an attack there is four times greater than at any other target." "Water supply?" "Sarin is a gas, right?" "It can be, but it starts off as a liquid that completely dissolves in water." "That's why using the water system makes perfect sense." "They don't have to spread the poison themselves." "They can let the city distribution do the work for them." "Let me talk to you a second." "Yeah." "What's up?" "What's going on?" "What's he doing here?" "Who, Dad?" "Yeah." " He's helping me." "He's been invaluable, actually." "No, no, no, Charlie, you can't do this." " I can't?" "Why not?" "Because, A: it's dangerous, B: people have been poisoned." "I mean, what are you talking about "why not?"" "You don't seem too worried that I'm involved." "Of course I'm worried you're involved." "Agent Eppes, I think we got it!" "Print from the glove box matches a print on file with Customs." "Josef Haliz," "Algerian National." "Homeland's already got a whole file on him." "Hold your fire!" "Hold your fire!" "I want these guys alive." "Let's go, back up." "Back up." "Need eyes and ears here." "Somebody's got to get me eyes and ears in there." "I hear talking; it's more than one person." "What are they saying?" "It's in Arabic." "Agent Eppes, we got video." "It's a lab." "They're set up for mixing sarin." "They're still talking, I can't make it out, Don." "Oh, they're praying." " Colby, get out of there." "Let's go, everybody, move in." "Move, move, move, move!" "FBI!" "Freeze!" "Damn it, we better lock this place down." "Let's go!" "Get out of here!" "We've got to evacuate!" "Let's go!" "Back down!" "Lock down this neighborhood!" "It's done-- the chemicals are gone, all of them." "At the very least, they've been making sample batches." "Worst case, the sarin's been fully weaponized." "Sarin degrades quickly, so once it's been mixed, they'd only have a few days to use it." "Clock just started ticking faster." "Yeah, you know what?" "We better get going on securing that water supply." " Yeah." "Wait a minute." "How do we know the water's their target?" "Because my math says so." "Is it really smart to put all our eggs in one basket based on math?" "Yeah, if he says so, it is." "House is clear, but we found these." "Charlie, check it out." "Dilution tables-- they were calculating how much sarin they'd need to toxify a large body of water." "We got to tell people not to drink the water." "It's not just drinking the water." "It's any contact with it, okay?" "It's a bath, it's a shower." "Even mist blowing off a sprinkler could be deadly." "Then we got to find the sarin now." "Yeah." "These guys certainly aren't going to be telling us where it is now." "Well, they didn't know." "Compartmentalized cells, remember?" "Right, right, okay, okay." "Their job was to mix the sarin and deliver it." "It's someone else's job to use it." " Right." "I know." "We keep going after these low-level guys." "We got to find out who's running the show, right?" "We got two players." "We got two pieces of the puzzle." "Get me information on them, we'll be closer to figuring out who the mastermind is." "Ah!" "There you are, Charlie." "I didn't know you were out here." "So, uh, where are we?" "Oh, I see." "We've ID'd two more terrorists, huh?" "How do they, uh, fit in?" "I don't know yet." " All the same," "I've been, uh, putting more thought into the actual poisoning, you know?" "I mean, to exactly how they would, uh, be able to introduce the sarin into the water supply, and the problem is, Charlie, the targets, like the reservoirs and the aqueducts-- they're just too big." "I mean, I'd have to think that a poison, even as potent as sarin would just... too diluted to do any damage." "Wouldn't it?" "Charlie, am I boring you?" "Don doesn't want you helping me out anymore, Dad." "What are you talking about?" "Doesn't want you involved." "He feels like this whole thing could get really dangerous." "Oh, come on, that's ridiculous." "How could it be any more dangerous for me than it is for you?" "Just telling you what he told me." "The, uh, mayor's office just received a list of demands from the terrorists." "They think it's authentic?" "Yeah, afraid so." "The demands are mostly political." "They want the release of eight suspected terrorists being held at Gitmo, removal of American troops from all Muslim nations, as well as millions of dollars in reparations." "These guys have to know we don't negotiate with terrorists." "Which means they're still going to do it." "They'll still strike." "Hey... hey, I think I got it." "You got what?" "I cracked the cell structure." "the dead chemists, the addition of al Dossari, the Algerian-- those were actually all the pieces I needed." "Charlie, you able to fill it all in?" "Not all of it, but I know who's on top." "Sharif al Maliki, who's a known terrorist." "You guys should have him in your files." "Now, wait now..." "Are you..." "Are you sure you got the right guy?" "He's at the nexus of too many lines of connection, okay?" "He's got to be the guy who's behind this." "I spoke to the CIA, Homeland, Customs." "The more that comes in, the more it looks like Charlie was right." "Same here." "You don't have to sound so surprised." "The list of demands names eight Gitmo detainees they want released." "All eight tie directly to Sharif al Maliki." "And guess who ran the terror camp all three of these guys attended." "Sharif al Maliki?" "Yeah, he's the sole point of connection for at least five of these players." "Yeah, it's not him." "What?" "He's dead." "He was taken out very quietly by a covert ops team in northern Pakistan." "Four months ago." "W-Wait a second, wait a second." "How do you know?" "Because I spoke to the NSA." "No." "No." "His..." "His name was the one name that kept coming up." "It's-It's his cell." "It's his operation." "All right, so where does that leave us?" "Hijacking." "No, Charlie, that notice-- it's been up there for about six months." "Remember, I told you the individual players are isolated." "How they know nothing beyond their individual assignments." "Right." "So?" "Well, that's the strength of a terror cell." "But it also presents a huge vulnerability." "Remember the example I gave the other night-- the baseball fans holding up cards to make a giant sign." "What if someone got hold of the designer's blueprints and made some changes?" "Remember, the fans don't know what the big picture is." "They only know what their individual jobs are." "Someone could take over, change the objective of the entire mission, and no one would know." "So, if Sharif had a blueprint, an actual list of names and numbers..." "Anyone with access could conceivably take control." "That's it." "That's exactly it." "Al Maliki's plan, the whole terrorist cell has been hijacked." "Agent Eppes, a decision's been made." "The government's going to make a payment to the terrorists in exchange for the sarin." "They'll wire four million to a foreign account now, and another four million when the sarin's returned." "I thought we don't deal with these kind of people." "Well, none of their political demands are being met." "No prisoner releases, no change in U.S. policy." "It's called an Iraqi Ransom." "Happens all the time with abducted soldiers or journalists in the Middle East." "A middleman surfaces, says, for a fee, he can get the hostages back." "Yeah, a middleman?" "Everyone knows he's one of the kidnappers, but a payment gets made, the hostage is released." "And the U.S. can maintain its claim of not negotiating with terrorists." "I guess." "I've seen it over 100 times while I was working covert ops in Northern Pakistan." "Hey, Dad, where's Charlie?" "He ran out to the garage to get a couple of files." "But hold on, I want to talk to you." "No, I'm in a rush." " Now, now, Charlie will be back." "Now, look, you're the son, I'm the father." "Now, that's not going to change." "So, until the inevitable," "I'll be the one to decide what is or isn't too dangerous for me to be involved in, all right?" "It's more than just a little condescending for you to tell Charlie to exclude me." "You're going to need what I know." "All right." " A lot of that current water system was built under my watch." " I'm sorry." "I don't mean to be condescending." "That's just..." " Hey, guys." "Charlie, you get anywhere with who hijacked the cell?" "Anyone who had access to the blueprints for the plan." "I'm thinking, like, one of Maliki's lieutenants." "Well, actually, no, no." "See, by the very nature of the way a terrorist cell is structured, everyone involved is intentionally given a limited perspective." "You know, if a bunch of kids are swimming in a swimming pool, and there's an adult in the swimming pool with them, even though he's closer to the kids, technically becoming part of their network," "he can't really see everything that's going on, so the most advantageous position for a lifeguard is outside the pool." "That way, he can see everything that's happening." "So, it seems to me that whoever hijacked this plan had to have had the wider perspective." "Right, someone outside the cell." "From whatever I've read about terrorist groups, the, uh, the leaders-- they insulate themselves." "So, who?" "Who from the outside world had contact with Sharif al Maliki?" "I got it." "I got to go..." "So, you were on the squad that did Maliki?" "What was that?" "Your team took him out?" "Yeah." "So?" "Yeah, so you knew he was dead, but you just, what?" "You let us waste our time." "Eppes, covert ops wouldn't be covert if we talked about them, now would it?" "I know all about you covert op guys with your accounts all over the world, and I also know yours happened to have just gotten $4 million richer." "Should we go have a little talk?" "Fine." "So, you found Maliki's blueprints after you took him out, right?" "Nice little chance to get rich." "I busted my ass helping you on this case." "If I'm behind it, why would I do that?" "So we'd know the threat was real." "That's the only way to insure there'd be a payment." "Either one of you have any idea the sacrifices I've made to help protect the people of this country?" "I know how you're selling them down the river for four million bucks, that's what I know." "I'm not making any admissions here-- none." "But... if I had done something like this, you can bet" "I'd be smart enough to make sure the sarin never had a real chance of reaching the public." "And how would you do that, Captain?" "Kill off the cell responsible for putting the sarin into the water supply." "The sarin gets mixed, delivered, but the plan never comes to fruition." "No one gets hurt." "Why don't you just relax, Eppes?" "Uncle Sam paid the money." "Hey, Don, let me talk to you for a minute." "What's up?" "The sarin is gone." "What?" "!" "Hazmat went to the warehouse-- the address we got in exchange for the ransom-- empty." "Nothing there." "All right." "So the sarin's not there!" "You're lying." "It has to be." " You tell me how no one's gonna get hurt." "Go ahead, tell me!" "I'm not saying another word." "How can this be?" " I've been saying for days that the terror cell is an adaptive system." "It's dynamic, the structure changes." "So somewhere along the line, a cell mutated." "We got new information on the house where the chemists mixed the sarin." "Evidently, they weren't the only ones living there." "How many more?" "The neighbors said they saw four men there yesterday." "That's the mutation, that's the change." "So it doesn't matter if the captain killed off the sarin delivery cell, because now another one has grown to replace it." "So someone else is going to put the sarin into the water." " Oh, yeah." "Yeah, this plan is still moving forward." "Hey, guys, come check this out." "...that the city's tap water may be contaminated." "City officials have offered no details as to the source or cause of the possible contamination, saying only that they suspect a ruptured sewer line may be to blame." "Now, in the meantime, they warn to avoid any and all contact with tap water..." "So they're blaming the sewer line." "Half of L.A.'s already gone to sleep." "They're gonna wake up in the morning, start brushing their teeth, taking showers." "Adams knows we got nothing on him but the money." "Yeah, foreign bank, no records." "I mean, if he stays quiet, he's actually got a shot at walking." "Hey, Donny." "Guys, what is going on?" "Charlie told me to come." "I did." "And this is Professor Osaki." "e's an organic chemist." "And a bit of a sarin aficionado,I have to admit." "Nothing personal, but, Charlie, we got plenty of experts here." "Donny, this is not a time to turn down help." "Fine." "What do you got?" "All right, look." "Based on the sheer quantity of water and distribution, we think they will hit, but not until after the water has left a treatment plant-- tap into one of the main lines somewhere else." "If they narrow it down to a single main, wouldn't that reduce the amount of potential victims?" "As potent as it is, even sarin can be diluted beyond effectiveness." "By using a single water line, they can maintain toxic levels to 15 or 20,000 homes." "That's over 2,500 miles of pipe." "I'm sorry, but I can't even begin to tell you what mile they'll hit." "All right." "Look, we need those blueprints." "I mean, we got to know where this attack is gonna take place." "You know what you're asking me to do?" "Yeah, I do." "You want me to incriminate myself, and I'm not so sure I can do that." "Listen to me-- tomorrow morning, thousands of people are gonna turn on their water." "That's mothers and fathers and kids and grandparents." "I mean, come on." "Captain, you've had a long, decorated career." "I mean, do you really want to go out like this?" "Is this really the mark you want to leave on the world?" "Okay." "Okay." "Got it!" "I got it!" "They're gonna tap into the main line in Hollywood near Vine!" "Charlie, push in on Hollywood." "All right, the Hollywood main runs right under Argyle." "Wow." "The water pressure in those lines has to be enormous." "They'd need a pretty substantial pump if they wanted to inject into it." "So they'll probably need a truck, which means they'll be easy to detect." "Not if they use the tunnels." "What do you mean?" "What tunnels?" "Well, they're old-- 60 or 70 years at least, left over from the Red Car railway that used to run all over the city." "So it's near the water main?" "Well, they'd have access." "I was down there once." "I saw a bunch of relief valves." "Charlie, would you punch in closer?" "Okay, now, the entrance would be about there." "All right, let's roll." "You get SWAT." "Let's go." "Good work, Dad." "This thing starts beeping, you get your mask on, all right?" "Don't have to tell me twice." "All right, so the air is clean in there." "We found a fresh set of tire tracks though leading back in." "Has to be their pump truck." "Means they're already inside." "All right, let's hit it." "DON:" "Hey, guys on the left, keep going." "We're gonna go up here." "Just keep going down." "Hey, Don." "There are tracks in both directions right here." "Couldn't make out enough detail, though, to tell which ones are theirs." "Yeah." "We got to split up." "SWAT, go left, we'll go to the right." "Let's go." "FBI!" "Don't move!" "Don't hit the truck!" "Don't hit the truck!" "The hose is leaking!" "No, no, it's just back pressure from the water main." "He's making a move for the pump!" "All right, we got to get someone who can cover that pump." "Make a move?" "Uh-huh." "I got the pump!" "I got it!" "Get the door." "You guys, all right?" "!" "Anyone hit?" "!" "We're okay!" "You stopped them." "If you only knew how close it came." "It wasn't just about the money." "I hope you know that." "There's a greater good here." "Oh, yeah?" "How you figure that?" "I exposed a terror cell hiding in Los Angeles... highlighted the vulnerability of this city's infrastructure, made people see the kind of danger we're really facing." "Oh, I see." "So, what, was this, like, some kind of drill?" "End of today, we're better off than we were yesterday, right?" "It's a net gain, no way to argue that." "Yeah." "Okay, get him out of here." "He handed over the blueprints to the entire cell." "We're already rounding up the rest of them." "Good." "You put in a good couple of days." "Night." "Good night." "All right, boys, good job." "Night." "Night." "Good night, guys." "Hey, what's up?" "I was thinking about you in there." "Yeah, it was pretty scary." "That's not what I mean." "I mean..." "I couldn't deal if something happened to you." "You got my back, right?" "Yeah, for sure." "Okay." "I got yours." "Coming over?" "Yeah, just want to check in with Charlie and my dad." "Ah..." "Well, I'll be there later." "All right." "All right." "See you later." "Ah, you guys are still up-- great." "Well, what'd you expect?" "So listen..." "Hey, we were watching the news, and they said that Emergency Services canceled the alert because the water's safe now." "Isn't it amazing-- they managed toever even mention sarin or terrorism." "Huh?" "I guess we're supposed to feel lucky that it ended the way it did." "Yes." "And that's why I came, actually, to thank you." "Thank you." "Muchas gracias." "Is that your way of admitting that you were wrong?" "No, Dad, I wasn't wrong." "I mean, look, you guys definitely helped." "I mean, and to that, we're grateful." "All right?" "I mean, I'm grateful." "Grateful?" " Yeah." "Grateful's good enough, then." "I can sleep on grateful." "What?" " When did this happen?" "This whole new attitude." "New attitude is gratitude." "Nice."
