@Druid @Shadowman311 if we're being completely honest, any random cop male or female would probably do the same thing if there's a guy running at you from the same place the shooter is lighting you up from. it's extremely unfortunate but if you don't take that shot and it turns out it was the guy, you're dead instead. it's much easier for us, looking from a bird's eye view hours later, to make that judgement call.
her partner going down crawls away while she's trying to hold position. running over to check on him at that point would be compromising herself.
running away and not neutralizing the threat, on the other hand, is the actual problem here. at the very least, you want to hold him there for as long as possible before backup can arrive. neutralize threat, then check on officer/civilian. you chose to be a cop, you chose to put your life on the line, you need to do that in order to protect everyone else then that's what you gotta' do.
