A link that explains how prevalent and entrenched corruption has become in the US:
If you think it's any better here you're out of your mind. Read the news. The Calgary Police force routinely is accused - and convicted - on similar charges. Maybe not as bad - but maybe - just maybe - we don't know everything that's going on. Probably. There's no fixing this, there's just dismantle it and start again. We can do a lot better.

This actually makes a lot of sense. You don't have to have lived in Calgary for long to see the police flashing their sirens to run a red light (for no reason other than boredom), make illegal turns, parked illegally, etc. And the whole attitude of "we're above the law" is pretty clear in any dealings with them. Accountability is the first thing everyone should expect from anyone paid to uphold the law...
