I like the one where a man who had memory problems carried a voice recorder to aid him in recalling conversations. The officer told him it was illegal to tape him, the man explained his condition, the officer still insisted he turn it off, the man refused, was tackled by another officer resulting in injuries to the man. The officers then refused to allow the man to record what his attending physician was telling him about his injuries!? It should not only be legal, it should be required that officers themselves record every official act involving members of the public. They are representing US and what they do is OUR business!
Nah, it's better if they mind their own business and let us do it if we want to. When they're in charge of the taping, the tape only appears when it supports their version of events. If it's bad for them, there are "technical difficulties".
