The police department didn't fire the chief; the city council did. And only after their hand was forced by bad publicity. If the police can only be trusted to do their job when the public is breathing down their neck, that would seem to indicate a problem.
You still havent cleared up when the police saw the video. That night, later on Youtube or a month later on TV?
That bit came from another article Google listed when I searched for "Justin Collison."
And now, you're as informed as I am on the topic.
Oh, gee!, the wrong people fired him! Guilty!!! Who usually fires police chiefs? The filing clerk?
So you say but you haven't shown any proof of that. You can't even say for sure when the police first saw the video.
