There was a time when police knew when to use force and when not to. Unfortunately, today leaving that punk alone would have made no difference whatever to the epidemic of police thuggery against law abiding citizens or their increasing disregard for the 4th Amendment. If it would, you might have a point. But it doesn’t, so you don’t.
The reason there is an epidemic of police thuggery is because they’ve been excused for doing it against criminals for so long.
Abuse and rights violations are like a cancerous tumor on the body politic. If you don’t cut the tumor out, it grows and spreads and consumes the body.
The fact that you can’t see that allowing the abuse of criminals leads to the abuse of non criminals makes you a sheep.
