Have a feeling the officer is going to walk. Horrible situation for everyone.
Found this on the inter-webs so take it as you will.
"It doesn't seem to me that there is any justification ever for shooting an individual who is fleeing in the back," said the family's attorney Fred Rabner. Mr. Rabner should know better. Antwon Rose was riding in a car that matched the description of a car involved in a recent drive-by shooting during which the person who was shot at returned fire and blew out the back window of the suspect car in which Antwon Rose was riding. Firing a gun in a drive-by shooting is a felonious act committed by someone in the suspect car. Sworn police officers are required by statute in most states, and by sworn oath in all states, to immediately apprehend escaping felons or persons committing felonious acts without fail, no excuses, no ifs, ands, or buts, and are authorized to use any and all necessary and proportionate force, up to and including lethal force, to do so. Proportionate force means if the escaping felon or person committing felonious acts shows or uses a weapon (or was reported to have used a gun, or threatens or gives the appearance of doing so - i.e., has the real or apparent means, including a hand/finger hidden in a pocket and pointed as if it were a gun, or aiming a moving vehicle at an officer), the use of equal ('proportionate') force is reasonable to apprehend that person based on the 'reasonable fear' produced in the officer's mind when confronted by the real or apparent presence or threat of the weapon (thus the 'Get your hands out of your pockets right now!' command given to Milwaukee Bucks basketball player Sterling Brown two weeks by the Milwaukee police, to which he stupidly relied 'No, I got stuff in my hands!'). Current firearms training is to aim for the center mass and fire until the gun stops firing (jams, or runs out of ammo), or until the threat has been completely and thoroughly 'neutralized', which often means 'dead'. Center mass is defined as the area from the 'neck to the waist', including the front, side, and back - there is no exemption from being shot in the back - and there is no obligation for the officer to wait until the escaping felon/person committing felonious acts turns around so he can conveniently be shot in the front - since the requirement is to apprehend without fail by any and all necessary and proportionate means any and all fleeing felons and/or persons committing felonious acts). If the facts, situation, and circumstances in this shooting as reported in the media are correct (sometimes a big 'if'), the shooting will be regarded as a 'justifiable homicide' - because the officer reasonably suspected that the fleeing suspect had committed or was an accomplice in the commission of a felonious act. i.e., the drive-by shooting. Those facts, if correct, make this shooting a justifiable homicide."
