According to FBI statistics, in 57% of active shooting incidents, police were at the scene before the shooting ended. When they first arrive at an active shooting scene, police face a quick decision, said Suffolk County, N.Y., Chief of Patrol Stuart Cameron, who has written several academic journal articles about police protocol when faced with an active shooter. Now, the Orlando, Fla., Police Department is facing questions about the length of time it took to end a shooting at the Pulse nightclub early Sunday morning. At that time, many officers were taught to respond to a mass shooting by simply containing the scene, preventing violence from spreading. At 5:05 a.m., a tactical unit stormed the club and the shooter was killed.
