"If I was carrying and he asked if I was armed, I said yes and he asked for my CCW, I'd show him. That is a lawful request. "
You need to qualify how you are carrying. If you are concealing, I agree. If openly, then no, it is not a lawful request.
"Once I showed it to him, I'd be on my way unless he had PC to detain me. "
If you are concealing he already has PC to detain you as CC is presumably illegal. If OCing, he does not.
"If he wanted to disarm me, he better
have RAS at least, or I'd sue in Federal Court."
If you are CCing he already has RAS and explicit authority to disarm. If OCing, he does not (outside another circumstance).
"The fine line is CC is a privilege, per the SC, and you may have to prove you have that privilege under reasonable man doctrine if you're printing, for example. OC, where not unlawful, is not needed to be defensible. Nor is car carry."
