I don't want to get into law jargon and semantics, but address a broader ethical standpoint.
If i understand this correctly, it seems that a suspicion (subjective) of one having a gun means that they are subjected to a search. I dislike the notion that there is an inherent negative quality associated with the carrying of a weapon. "He might have a gun, so he's probably doing something wrong." If that sort of rationale was applied to any other form of tool, it would be laughed at. "He looks like he's holding a powersaw, he must be ready to commit a crime". It intrinsically labels guns to have no other purpose but crime and the only way to prove that you are not doing something illegal is to have a state approved form. We are all mindless criminals holding toys we don't understand unless Uncle Sam says we can take it out of the playpen. It's offensive.
I told the new me,
"Meet me at the bus station and hold a sign that reads: 'Today is the first day of the rest of your life.'"
But the old me met me with a sign that read: "Welcome back."
