Still illegal in VA.... yeesh
?? So is having public sex with a trio of Unicorns... In public view.
If you 'hide' your detector in your tank bag per my post, Officer Friendly will have narry a clue. The cable to your helmet is just audio from your iTunes thingy, only *IF* you decide to tell him/her that is what it's for. I highly advise you don't though. Especially since most every modern detector can *not* be found via whatever EMF/EMI/Super-hetrodyne tool the Federalies have. Commonly called a "radar detector detector".
If they ask to inspect the contents of your tank bag, they need a warrant. If they do get one, not likely for a trivial traffic stop, they'll also find 103 pounds of crack, a bottle of Quaalude's, and a tin of condoms (see Unicorns above). Note that the latter is not illegal, though it may be questionable.
