Police Chief Brian Manley said a new tactic used at this protest was a number of vehicles following the mob, which blocked police cars from getting close to the agitators. When a police car attempted to get closer to the shooting scene, one of the cars blocked it from going forward. It does not appear that any of the drivers who where blocking police cars were arrested, nor were any of the agitators blocking the street arrested.
