> If you disagree that nakedness should be illegal that's a different story and has nothing to do with the police
I do question the logic of nakedness being illegal (in many cases anyway), but I agree that's a different story. :)
> Are you suggesting every person to decide what's allowed and what's not to the best of their judgment?
I'm assuming the case you mentioned at Harvard was this one: https://slate.com/news-and-politics/2018/04/cambridge-police...
So who gets to decide what "reasonable force required to arrest someone who is refusing arrest" is? You really think that repeatedly punching someone for being naked and on drugs is reasonable? Why? Why not just detain him and work on getting him to a safe place? Why does the situation warrant violence at all? Just because it's common in this country does not mean it's justified or ethical.
What if they had shot him, or knelt on his neck and killed him? Would that be "reasonable"? Where, then, is the line?
Right now, cops basically have 100% discretion to decide where that line is. Because they are not actually accountable to anyone but themselves, they just act and draw the line after the fact. The only difference between this and the murder of George Floyd is degree. That's what I meant.
> If you use common sense then indeed you should try your best to avoid violence in illegal activities that don't put anyone in danger
I agree in the abstract, but unfortunately there's a racial element to this "common sense." In the US, black people especially must use a different kind of common sense, and must always remember that any kind of transgression - up to and including "looking suspicious" - is grounds for detention, which can escalate arbitrarily to execution on the spot. So there's really no "avoiding violence" when your mere existence is grounds for murder with no consequences.
And again, just because you can have a "reasonable" expectation of violence from the cops does not mean that violence is justified.
> the police has no choice
Well, they had a choice to not become cops in the first place, to not enter a system that lacks accountability. They have a choice to not enforce unjust laws, especially in situations where no one's in danger. They have a choice to challenge their colleagues to justify their actions, whether that's kneeling on someone's neck or punching them in the stomach. They have a choice between violence and deescalation.
But they choose violence and escalation with alarming frequency in this country. And the system protects them.
