So at what point do citizens say enough?

Is it when cops taser a man with a broken back 19 times because he can't get up? http://www.newshoggers.com/blog/2008/07/cant-think-of-a.html

Or is it when a police SWAT team shoots to death the two dogs of a town's mayor during a no-knock raid? http://www.washingtonpost.com/wp-dyn/content/article/2008/07/30/AR2008073003299_2.html

Or maybe it's when witnesses who don't parrot the police side of the story are detained, interrogated and intimidated: http://www.reason.com/blog/show/126284.html
