I found this article on Reddit about New York.
They're creating a connection between video surveillance and quality control of the police force. Personally, I feel they aren't quite the same and get a bitter taste in my mouth reading it, but I can somewhat understand what they mean. Judging from the article, which is quite one-sided, the police force does seem to get a bit power hungry.
Personally, I don't see any of this behaviour here in the Netherlands. And honestly, don't expect it anytime soon. Since we got an abundance of Americans on this site, I was wondering what your opinion is about the article, and perhaps have a few personal experiences with these cases.
