Try snapshot today -- no pressure. Inside for the look of culture of bikers. After the violent incident on New York City. That family surrounded. Many bikers say that painted an unfair portrait of them. The land mark, those bikers say is fair game. Night line going in depth and here's ABC juju Chang. Reporter: Some of us like to play by the rules. Others like to break them. Chad Walton is a rule breaker. Until you ride with 1,000 bikes and ride through a town, there's nobody in their right mind going to try to challenge you. Every city has its lands mark. Chad plans to lead hundreds of bikers to block the bridge. Stop traffic and take it over as a private playground for stunt biking. They know the police are on to them. So three nights before the event they're figuring out how to get away with it. If you're at the front of the group and you see a roadblock here, bring the whole bring and just butt into the Trees man. Law enforcement plans to show up in force and stop the shutdown. Do you anticipate conflict? I hope not. They have got to understand what our job is. It's law enforcement and it takes one little tiny thing and we got a 10 car pileup. We have at least 10 -- helicopters will be out there. You're preparing for the worst. We are. The night above the shutdown they gather for a warmup ride. If you want a ride, raise your hand. The ride is on. The plan, antagonizing the police. We really don't act up on it. Nothing crazy. One of the bikers is signaled by police to pull over. Instead he makes a run for it with a camera still left on his bike still rolling. Once on the highway he tops out at 170 miles an hour. The police never catch him. Tonight she's have more on how that played out. Tonight premiering at 9 eastern 8:00 central on ABC.
