So, who is going to try cops when they are corrupt?
By what mechanism can we the people enforce the law on our own government?
It seems silly to go before our own government and beg for them to obey their own laws.
Sometimes we get lucky- like gay marriage- but how many decades did that take? It was 1980s when the supreme court ruled that sodomy could be criminalized on the basis of "a thousand years of christian tradition" (namely NOT on the basis of the constitution.)
So of course, we will continue to see more and more corruption until like AIDS is now, and the wars overseas -- the news simply stops reporting about it, because it has become the background noise of the society we live in.
That's going the wrong direction.
I'm far more afraid of being killed by a random cop than I am by Walmart or anything in walmart. They all have an incentive to keep me safe so I'll keep buying. They would face consequences (not even criminal, just market consequences) if they were killing people.
Cops on the other hand, they get away with it. And blatantly do day in and day out.
