Good lord I hate the "what next" brigade.
Whilst some do bring silly levels of conjecture they all have one valid point. These kind of laws are nearly always the thin edge of the wedge. If people don't rise up against it they'll just push for tighter laws.
It's the people who cannot see the danger in laws like this, those who spout the tied diatribe of "if you have done nothing wrong" that are the bigger problem here. Governments are always going to try the push the legislatory boundaries, often in the name of safety or security, but if they are allowed to get away with it and we sleepwalk ourselves into a police state who is ultimately to lame?
So I'd rather have more "what next" types than have more "nothing to hide" types.
