Have been arrested. Nine fatalities after the worst single outbreak of violence since thein 20 years. Dozens of knives, firearms, one crowded restaurant, alcohol, a rivalry and a spark. Reporter this is the aftermath of a deadly battle involving at least five rival biker gangs and texas Law Enforcement. Shortly after 12 15, a fight broke out in this building into the parking lot as twin peaks. As that fight progressed it progressed rapidly from hands and feet as weapons, to chains a club was involved and knives were involved. Gunfire broke out on the part of the criminal biker gangs. As the bloodshed spilled into the park lot, Police Including s. W. A. T. Officers who had been monitoring this bar for biker gang activity, moved in. As we pulled up on scene, the shooting at individual bikers from bikers turned toward us. Our officers took fire and responded appropriately, returning fire. When the shooting finally stopped, nine bikers were dead, four of which according to a Law Enforcement source may have been killed by police. Whats still unclear is exactly what led to the fight between these rival biker gangs. What is clear is that the bloodshed could have been worse. Twin peaks is in the middle of a busy shopping district. Just imagine this. On sunday this area teeming with innocent bystanders completely unaware that a gunfight was about to erupt. Reporter police say the restaurant itself is partly to blame. Management knew there were biker gangs, they continued to let those groups of people into their business. We feel like there may have been more that could have been done by a business to prevent this. Now we have nine individuals that are dead, and it wasnt necessary. Reporter beyond the nine bikers killed, around 170 were rounded up and arrested. So many suspects they initially had to be bussed here to the Waco Convention center before being processed into the county jail. Those individuals are being charged with engaging in organized crime in reference to the shooting at twin peaks, which is a capitol murder. Its a capital murder because of the number of victims that were killed in one episode here. And tonight, authorities fear reprisal attacks against the among the biker gangs. Or revenge attacks against Law Enforcement themselves. It could continue the bloodshed in waco. Nick valencia joins us now from waco. More violence a concern as you mentioned, what is the latest on that . Law enforcement officials here on heightened alert saying there may be a chance they will be targeted by these biker gangs, saying a green light hit has been put on all officers in uniform. Cnn retaining a statement from the local owner of the twin peaks in waco, texas telling a different version of events than what police have been saying. To the best of our knowledge, Law Enforcement officials did not ask the waco Restaurant Operator with whom they spoke several times or the twin peaks franchiser to cancel the patio reservation that was made on sunday. Based on the information to date, we also believe that the violence began outside in the area of the parking lot and not inside our restaurant or our patio as has been widely reported. So you see, anderson, a much different version of events from the owner here at twin peaks in waco texas. Anderson . Nick, i appreciate the reporting. Just to underscore how volatile this mixture was, all this went down despite as we mentioned a heavy Police Presence nearby, it was a visible Police Presence. Heres Police SpokesmanPatrick Swanton. They could care less whether we were here or not, thats the violence we were dealing with yesterday. They knew we were seconds away, and were going to respond. It mattered not to them, they were still killing individuals, and then turned their gunfire at us when we got here. Sergeant Patrick Swanton joins us now live. Sergeant, thank you very much for being with us. First of all, i want to ask you about this report, about others coming to the waco area, what are your concerns, what do you believe may happen . We think thats a possibility. We saw very early on last night, that we had a contingent of bikers coming into the area, a larger amount than we would normally see here. When the threat was put out toward Law Enforcement officers, caused us to really step up our game. Obviously, its something were concerned about, we would encourage biker groups to stand down, theres been enough bloodshed, theres been enough death here. We dont need additional death in the waco area. Obviously, we were still sorting through the scene behind us, well process that evidence and continue the investigation through the coming days and weeks. Do you know what it was that actually began the fight . Because now the restaurant is saying the franchise is just saying it didnt happened inside the restaurant or the bathroom. They believe it happened out in the parking lot. Do you know what actual caused this . We know it started in the bathroom area initially, there was also a skirmish in the parking lot, i dont know how close those two were together. There was shooting inside the club, i wont sit here and argue with an individual. But i can tell you that we believe the shooting occurred inside, moved into the open bar area and came out into the parking lot as well. Nine individuals were killed in that parking lot, and were in the process now of trying to determine exactly who all was involved, and specifically what this started over. We believe its gang related activity, whether its to determine some turf for one group or whether its in the process of recruiting for another group, all of that kind of goes hand in hand. It may have been one gang trying to say, were here in your area, and were going to be here because we want to. So i mean, because these are gangs that do have a longstanding rivalry. So the fact that they were all in the same area, is that unusual . That theyre all in the same area at one time . Its a little bit unusual. Obviously when you get groups together that cant get along, we know theres a history between these two groups. We know theres a recent history of violence between these two groups, that may have played a part in what occurred here sunday as well. I want to ask you about something the local twin peaks franchise said today, they said that Law Enforcement officials didnt ask either the waco Restaurant Operator or the franchise to cancel what they called the patio reservation. I know you had been critical of this particular franchise, is that in fact true . No, what theyre saying is not true, and we dispute that fact. And in terms are they being cooperative now in terms of cooperating with the investigation at this point . I know you had said before they had not been cooperating. I can tell you national is being very cooperative at this point. We appreciate their efforts. We appreciate their news release that they have done indicating their willingness to work with us, and we think that will go a long way in healing some issues here. We are very appreciative of their support that they have shown us, and im talking about the national. They have revoked the individuals permit here today. Were pleased that they did that and they appear to be cooperating, we want to thank them for doing that. I know youve recovered a huge number of different kinds of weapons, guns and other kinds of weapons, do you have a lot of Video Evidence that can help you make this case . Because some of these charges may be hard in terms of assigning individual blame for activities. We have a lot of evidence. Whether Video Evidence is part of that or not, i cant tell you, i dont know. Okay. And just in terms of the sheer number of people you have in custody at this point, how difficult is that even to process . Extremely difficult. The Sheriffs Department is doing quite a job in trying to get them all through there. Youre talking about 170 individuals that need to be fingerprinted, booked in through paperwork, have mugshots taken. Last i checked about an hour ago, they were halfway through that. That will be a process as well for them to continue into the night. And your message to any gang members that may be thinking about coming to waco is what . Obviously, theres a heavy Law Enforcement presence here. Weve seen enough violence in our town over the past day, we would encourage them to just kind of stand down a little bit. Theres no point in them coming here to try to get pay back, whether its on rival bike gangs or against us. We would ask them to take a cooling off period and let the healing process begin. I appreciate your time tonight. Thank you. I want to talk more about the scale of this from a criminal justice point of view. Its breathtaking, the prospect of making dozens and dozens of major cases, murder cases is what theyre talking about when all is said and done. Joining us now is our senior legal analyst jeffrey toobin. How tough is this . You have 170 some, closer to 200, all in custody charged with capital murder. Is there any way theyre going to be able to successfully prosecute that many people . There is a way, but i have certainly never heard of a case on this scale anywhere. Big city, medium sized city like waco, small town, ive never heard of it. What they will have to do is figure out a way to isolate the evidence against each individual. Whether they can do that, i dont know. You asked a good question, is there any video, certainly that is going to be the most valuable kind of evidence. Remember most of the witnesses are going to be other gang members who to put it mildly may not be the most reliable witnesses. To say this is going to be a difficult prosecution is an understatement. I mean, you assume they must have some sort of undercover personnel inside with some of these gangs, because of some of the information, it seemed like the advanced information they have, could prosecutors charge a conspiracy . And if so, how would that play into these murder charges . How would they actually prove that individuals acted in a way to further conspiracy . Certainly that is a possibility. But even in a conspiracy case you have to isolate evidence against individuals. To prove a conspiracy you have to prove that an individual agreed agreed with the other conspirators to participate in an illegal conspiracy. And you also have to prove that they took an overt act, that they did something. It doesnt have to be an illegal act. But they have to have done something. They have to have done something, given someone a weapon, they have to have made a phone call, have done something in furtherance in support of the conspiracy. So again it folds back onto the original problem, which is isolating the evidence against each person who may be prosecuted. And with a melee like this, its going to be very difficult. Is it possible the owner of the franchise, whether the National Owner or the local franchise, could end up facing some kind of charges here as well . Police have been very vocal and critical, not only disputing what theyre saying about where this began, and the level of cooperation or lack of cooperation theyve got, but theyve been critical all along of saying theyve been reaching out to this local franchise, asking them not to host these events and they got rebuffed. Certainly the owner could be liable for some sort of civil liability, under a theory of negligence carelessness. Im not sure i see a criminal case against the owner based on the evidence ive seen. There doesnt seem to be evidence of criminal intent. Theres just simply an intent to bring a lot of people into his or her restaurant, and that created a disaster. I think criminal charges against the owner, at least based on what i know now seem pretty unlikely. Jeff, i appreciate the update, thank you. Quick reminder, make sure you set your dvr, you can watch 360 anytime youd like. Coming up, the violent rules that these outlaw bikers live and sometimes die by. Youre going to hear from two men who infiltrated some of the countrys most violent gangs. And later, a murder mystery in a d. C. Neighborhood that these flames may have been meant to cover up. Police have a person they are looking for. We have late details on that. Its delicious and this new kibble blend is so healthy. Thank you. No, nancy, thank you. Kibbles n bits. Because every bit matters. The real question that needs to be asked is what is it that we can do that is impactful . What the cloud enables is computing to empower cancer researchers. It used to take two weeks to sequence and analyze a genome; with the microsoft cloud we can analyze 100 per day. Whatever i can do to help compute a cure for cancer, thats what id like to do. We all enter this world with a shout and we see no reason to stop. So cvs health is creating industryleading programs and tools that help people stay on medicines as their doctors prescribed. It could help save tens of thousands of lives every year. And that would be something worth shouting about. Cvs health, because health is everything. Dear stranger, when i booked this trip, my friends said i was crazy. Why would i stay in someone elses house . But this morning a city ive never been to felt like one i already knew. I just wanted to thank you for sharing your world with me. It felt like home. Airbnb. Belong anywhere. The breaking news tonight, texas officials warning that more outlaw bikers armed and dangerous, could come to the state. The fear, reprisals against other gang members or Law Enforcement. Even if that does not come to pass theres no exaggerating what has already happened in waco. For a short time, it amounted to close combat, what in a military context would be several platoons or even a small company. Motorcycle gangs are not military units. Many are not violent. Even the groups involved in the mayhem yesterday also take part in other activities like toy drives and charity rides. That said, the Justice Department says the group thats tangled in waco have been on the radar at the Justice Department and with Law Enforcement around the country. More on their world now from sara sidner. This man is in a position to know just how dangerous biker gangs can be. Cloaked in darkness, he agreed to speak with us. He spent five years infiltrating three different biker gangs for the dea. The bag os mongols and outlaws. How would you describe how they operate . Are they different in the way they operate . Theyre very similar. Very sophisticated, structured like the military, a lot of members are exmilitary. So theyre highly trained for combat. Theyre much better than your average street gang at conducting war. When you talk about war, who are they warring with . Is it just other gangs or society at large . Id say its society at large and mostly other motorcycle gangs. Thats terrifying. Yeah. And a lot of these gangs when i did my bag os infiltration half my chapter was exmarines. So they theyre highly skilled, highly trained killers. Charles falco and an author and now consults for Law Enforcement on biker gangs, and said a month ago he was asked to go to waco because of growing tensions between two gangs, the bandidos and the cossacks. The bandidos are the biggest motorcycle gang in texas and they dont allow other motorcycle gangs to enter that state. Reporter this is the worst violence seen in years affiliated with biker gangs. This is the chaos shown in a nevada casino as three people are killed in 2002. Shots are being fired in the hotel. People are being stabbed. Reporter rival gang members shoot it out, leaving the casino crowd dodging Bullets Police forcing everyone to the ground as they try to sort suspects from victims. In 2011, shots fired at another casino, this time in sparks, nevada, when its all over, a member of the hells angels is shot dead by a rival gang. The violence between gangs hasnt stayed just in the u. S. Violence exploded between the bandidos and the hells angels. At one point the bandidos accused of using a car bomb and a rocket propelled grenade against their rivals. In america theres a way to quell the violence keep known gang members from getting concealed weapons. The problem were seeing now is in states where youre allowed a concealed weapons permit, the biker gangs have been ordered by their leadership to get a concealed weapons permit if theyre not felons. Right now, in most of these states where they have concealed weapons permits, gang members can get concealed weapons permits, theres nothing to stop them. Reporter but he said the bloodbath could have been avoided. If only the restaurant could have listened to Law Enforcement and mandated bikers could not wear their gang paraphernalia. The biker gangs wont show up, because they always have to wear their colors. Reporter sara sidner cnn, los angeles. So five societies with their own rules and codes of secrecy and violence. Atf agent billy quinos that world firsthand having spent more than two years under cover, posing as a member of the mong ols outlaw gang. The true story of the undercover agent who infiltrated americas most violent outlaw motorcycle gang. Because he still has enemies out there, were not disclosing his location were glad he could join us tonight. In your two years undercover with the atf, with these biker gangs, have you ever seen anything like this, this scale . During my two years undercover, i never saw anything like this, we had runins with the hells angels, nowhere near this scale. Not at all. The biker gangs are confronting each other, and the violence occurs with them all the time, just not to this magnitude. Why would they be all together . If there is this tension between them . There was a Coalition Meeting going on. Thats the reason they were all there. It wasnt just the cossacks and the bandidos that were there. There were a number of other clubs that were in this coalition, and they got together to try to iron some things out. One of the things that they were going to try to iron out, from what i understand was this turf battle or the right to wear the texas rocker out there. And things went from bad to worse, anderson. What i understand it all started over a parking space. But the cossacks and bandidos had been at each other for the past six months over the right to wear that texas rocker out there. Theyre fighting, beyond just
