Yes, actually, they do.
When I was a trooper, there were classes on DV sponsored by NOW of Florida. We didn't get paid for going to these classes (purely voluntary), but, hell, I wanted to be a good cop. They stressed, at length, that rapists were 99% men and victims 90% women (neither of those are true), and that women only act violently in self-defense, and that any man who tries to say his wife or girlfriend is violent is probably the abuser who's trying to muddy the waters, or he has abused her before that is why she's become this way, and we should take that into consideration.
And you know what? I believed it, and I wasn't the only one.
Now I know better. I don't KNOW that they're still teaching the same sexist bullshit, but there were plenty of data points proving that as sexist bullshit at the time (data points I wasn't aware of until later, but WERE in existence), so if they were peddling known bullshit at the time, I don't see why they would change now.
So, if you want to know why police give men 'the back of their hand', that's why. They've been taught to.
