Exactly my reaction.

> I'm [..] a man pinning screaming woman to the ground in a public place

I can just imagine how this goes down. You grab the perpetrator, wrestle her to the ground violently. You have to lean deeply over her to restrain both her hands. The victim runs away. The woman you're holding starts to scream and shout that you're assaulting her. The police arrive.

You are fucked with a capital F.

> a man [..] beating a woman in public

... the victim runs away. The police arrive. The police tell the other guys in the holding cell that you're a woman-beater.

You get the picture.
