I suspect this is totally unconstitutional. I’ll bet they are getting voluntary compliance from the ignorant public. All you have to do is REFUSE. Why should you have to LIE?
1. Refuse to answer as to whether or not you even have such a device.
2. If you have already said, yes, then refuse to allow the LEO to look at or examine your communications device. They have no right to do so.
REFUSE TO BE INTIMIDATED.
S.N.U.U.
Situation Normal, Utterly Unconstitutional.
