Not to say it couldn't happen to a male officer, but at least he would have a chance.
If you are referring to the video I’ve seen (in which a black male perp with his daughter in the car beats up the female cop that pulled him over), I believe she was out after one punch. I don’t think she recalled anything of the incident, either.
These women want to play man because it is a lucrative job (especially today); the sad truth is they can’t do the work. Here in NJ they eliminated the boxing ring segment of state trooper training after a female cadet was killed in the ring (the logic for that training was that state troopers are often alone in their cars); rather than address the problem we just pretend it doesn’t exist.
