That's absolutely insane, discharging firearms in the direction of civilians. Think about what you're suggesting and the consequences if someone moves as the shot is being taken.Yes, I have seen the clip of the civilian being dragged off, the terrorist was pinned down with him on top, the police could easily have shot him in the head at point blank range if they considered a threat to life. Messy, but letting the guy get up as an alternative?
Besides which, they didn't let him get up did they? He tried but he remained very much on the floor.
