You didn't actually answer anything I said. Do these people who you confidently say won't get justice go to the press? Do they call the DA's office, get out and advocate and protest, talk to their reps, etc? Or do they tweet about it? The stock answer is that a lot of them are poor minorities who won't get help no matter what. But that's what organizations like the ACLU et al. exist for. Get them evidence and let them fight.

Police are protected from the consequences of their own actions to an extent, and for obvious practical reasons. The necessary evil of responsibility coming with power is something we humans haven't solved in ten thousand years of trying.

With the current expansion of police/military power within the country, and the utter lack of respect for public opinion at the very highest levels of government, I think that this is a good thing. I don't disagree that it's happening.

What exactly do you think is a good thing? That no one in this country respects our police force? That the police are increasingly isolated from public opinion (like, as you say, our politicians)? That there's a huge disconnect between what people want from the police and what they get? How could that ever be a good thing?
