You're completely missing the point. Yes, the American criminal justice system needs a lot more reform, and yes progress on civil rights issues is painfully slow. No shit, congratulations for noticing.

There are millions of people in this world who care deeply about humans rights, and these people are the only reason any progress is ever made, whether in America or China or anywhere else. Do you really think you're helping by shitting on them because the progress hasn't yet achieved your satisfaction?

If I may offer a suggestion, either do something to join the fight, or shut the fuck up about it.
