content: Computer Chair Rambo over here.  You point out some better techniques in there, but to say he shouldn't be returning fire because people are around is unfair.  While ricochets can go anywhere, it was mostly empty street in the direction of fire. People /houses were perpendicular to where the bullets were heading. Also, you could say his shots were made in an effort to end the perps threats/shots, so it kinda washes out with the risk to the community.
