"Stlhead,

Your examples differ fundamentally because they violate civil liberties with invasion of privacy, unreasonable search without probably cause. I would be hard pressed to say that the 9th Amendment (since the 4th doesn't either) prohibits my being caught running red lights or speeding by use of technology instead of police manpower"

Salmo, if they are violations of civil liberties why are they done today? One brick at a time and we sheep will gradually give it all away. Is catching dangerous speeders a bad thing? No. But if they set it to 5 mph over are you catching dangerous speeders or just trying to generate revenue? I think the latter is behind this.
