i don't know. Legalities are pretty intrinsic to the situation. Unless I missed something, the shots were on the *fleeing* suspect.
That not cool... These guys are not law enforcement, and we do not carry to help enforce laws.
Very cool, shots on a suspect endangering the lives of other people in the public, then checks his 6. Now why he checked there is uncertain. He may have spun back toward the crowd because something was yelled to him, not because he is all tactical and doing the right thing. Without sound, it is hard to know.
