Detectors are illegal in Virginia and there’s a large sign at main highway entry points stating that fact.
Yeah...CT too. But here in MA they are not. I think the 'legal' states outnumber the 'illegal' ones.
That's interesting, because I remember a case several years ago where a state supreme court decision came down allowing the use of detectors. I don't remember the state, but I remember one specific line in the decision, to wit:
"If the police choose to use surreptitious and clandestine means of surveilling the public, this same public has a right to learn of the surveillance by any means available."
Whether this could be used today in a case in a different state is beyond my knowledge, but there it is.
For a passive device such as a radar detector to be illegal is patently absurd. I doubt it could even pass Constitutional muster.
