This should be humiliating to this guy. If I were a responding officer to this, I would have laughed at the guy and told him not to bother calling if she started throwing hard candy.
Statistically, an enormous percentage of physical abuse is done by women against men - and they get away with it precisely because there is no legal way to deal with it. Women can be verbally, emotionally and physically abusive, and then instantly claim victim status and win without ANY evidence, and they know it.
I say this guy showed a lot of courage. He didn't punch the crap out of her, and he faced up against the humiliation she was counting on him being afraid of, and called the cops and got her sorry excuse arrested.
And he did it when he was no doubt totally enraged. THAT's being a man.
