.. about the grey areas between annoyance and crime, intent and effect - if I read you right. I'm glad though that tailgating is now a crime in New South Wales - I think it's called 'menacing (or threatening) driving'. Hard to prove, but at least it's now legally acknowledged. I personally know people with whiplash - their cars had been (presumably accidentally) rammed by tailgaters.

Umm .. I'm not sure though what any of this has to do with 'Big Brother' - you seem to be saying that crime prevention is important, and then diverted into a ramble on defining 'crime'. In any case, the issues you raise do show that we - as mere fallible humans - shouldn't have that level of control over each other.

And yet - it might be necessary, because of terrorism and social violence generally. That's my problem with this issue - I can see & accept both sides of the argument.
