At first I was with you on this but a closer look shows that she was taunting the police, trying to get their attention or anger them in some way to overreact toward her. Start there and then place blame for the punch/slap if you must but don't start with a lie.
There is no evidence she was taunting anyone. That is your latest theory to divert from the clear evidence of battery.
Try again.
“He should not have hit her.” Period. There is no excuse, no justification that makes woman-beating acceptable.
Conservatives understand this.
Progressives defend woman-beating.
