Which is why every European country except Germany has dozens of cameras on every corner?
Yeah, nice theory :)

I wouldn't worry/care about individual hackers, but even if you have complete trust in everyone who has or will have legal access there are a lot of organizations for which hacking cameras one-by-one (even if hacking is actually needed) is well worth the effort.
I know your idea is the same as that of the USA law, but that really doesn't make it right
