Ammoland reports on Maryland's gun owner license code...
You may find that situation uncomfortably close to reality if you live in Maryland. Legislation introduced in both the state House and state Senate will require that gun owners have a special license to purchase handguns,
UPDATE: SaysUncle notes that he can't find that language in the bill. I looked, and I can't find it either; in my original post I was relying on the summary at Ammoland, specifically this language:
It is uncertain whether or not a "gun owner" designation on a driver?s license will constitute "probable cause" to search a vehicle during a routine traffic stop.It could be I jumped the gun a bit by not checking the language myself.
