Yes, the amount of force the police officer used was excessive. Let's not pretend Floyd George was a good boy, who dindu nuffin.
As an example, I'll use a situation that happened to me as a kid.
Just to let you know now, I was a dumb kid who should have known better.
I was pulled over on my way home from a friend's house. No, I don't remember why. I had a knife on me, one that was illegal to carry that my friend gave me. Upon being seated on the curb, and asked if I had any weapons I told them I did and lifted up my shirt. The cop looked me dead in the eye, and told me "Don't reach for that knife, or I'll put my boot in your face."
Moral of the story? He might have been a dick for saying that without taking my character into account. I, however, was not in the right either for carrying that weapon.
As much as I did then, George got himself into that situation. That's also why his being a porn actor should be taken into account.
There will always be rogue actors. Priests who molest, nuns who abuse, cops who are racists, etc. The left and the media sensationalizes rogue acts to make them seem mainstream.
