Radar Detectors

Over at Too Conservative, Riley is pointing out a bill proposed by Del. Joe May to make radar detectors legal in Virginia. We are the only state to ban them.
I think its a good idea, the cops have found ways to negate the use of them anyway.
The problem I have always had with this is that you usually only get a citation for a radar detector if you are pulled over for speeding. My question is, why are you getting a speeding ticket with a radar detector? Kinda defeats the point right?
I hope May's bill passes.
