I read where a bartender said there were two shots that left everyone thinking it was the music, a pause, and then rapid gunfire started that sent people ducking and scattering. A few vids online outside the club let you hear the bullets in rapid succession. SMH.
The bartender and a bunch of others ran out of back doors, so I don't think there were people outside blocking or shooting.
The fact that it took him three hours to be shot by cops means those people were trapped there for what must have seemed like an eternity, full of fear and watching more people die. :(
