But this totally invalidates his argument; if you're not recording everything, then who knows what's going on? And if you're filtering for "good stuff", then crooks can find out what you filter for and use that to avoid being caught.

You do, of course, have some evidence for that and it's not just an unsupported assertion? No, didn't think so.

Uh, there is no question that the US government has been "taken over"; the evidence is shown on TV shows every day. Knowing it's happened is not the problem. Getting rid of the crooks after they take it over is a problem, especially if they have a ubiquitous surveillance system to spy on their opponents.

Exactly. To someone who works in the film/video industry, this whole idea of trusting video is laughable. IMAX film will be trustworthy for a few more years because of the massively greater resolution; video 'evidence' is a joke.

Whoopee-do; I take my VCR, plug it into the surveillance camera so that the feed is coming from the VCR rather than live video, and the camera will digitally sign the fake video from the VCR. Or I take the camera apart, steal the key, and use that to create fake video from scratch. This is not a big deal.
Without universal surveillance you can't stop people doing this. With universal surveillance you can't trust the data because anyone can get the encryption keys and stick fake data into the system. Either way it's useless.
