Onc again, have you ever had to restrain a spouse or girlfriend? It is one thing to restrain someone who isn't attacking you, such as breaking up a fight. I've done that many times - I'm 6-7 and can get my arms around just about anyone.
It is another when a raging woman is coming at you. And the cops will be showing up with laws saying that someone needs to go to jail - and whoops, she has the bruises on her arms because she fought you restraining her.
Look, I'm not saying how to keep your nose clean legally, never did. Everyone has options and the situation and your judgement will dictate which ones you choose.
