“Technically if this guy had said, you just slapped me and my face is now red and swollen and it hurts, it could have been assault. And then the cop would have said it was necessary force due to the suspect resisting. “
Reads like satire.
The law gives cops the benefit of the doubt. Obviously it’s not ideal in all situations, but you have to legislate for society as a whole, not the individual. You can’t stop bad cops from getting hired, you can only try to minimize their damage.
