From what I read in this article and what I've read elsewhere, the police knowingly broke the law. How do we create a system in which police can and will be charged when they break the law? As long as they can act with impunity, they will always be above the law.

On a related issue, how much did this cost? Would that money not have been better spent on a few hot meals and maybe a warm-up shelter with washrooms and shower facilities?
