Not according to the people I've known from China who have told me that the state almost never does anything like that to individuals (excepting billionaires who used their money to harm people) but will crack down on corporations, and that is just the opposite of what the US does. Look at the founding members of the BLM movement in Ferguson. Murdered. Wasn't one ruled a suicide who had two shots to the back of their skull with their car set on fire while they were in it? Or Fred Hampton of the Black Panthers who was shot to death in his hotel room bed by cops? I think you have it a little backwards. But yes, both countries are flawed (one much more than the other if you're just a regular person and not a billionaire).
As for your last question, that's easy. Cuba.
