I carry WHEN I'm "allowed" to. The CC License I have says "a person is guilty of a misdemeanor when he carries to or while at a public gathering any explosive compound, firearm, or knife designed for the purpose of offense and defense. 'Public gathering' shall include, but shall not be limited to, athletic or sporting events, churches or church functions, political rallies or functions, publicly owned or operated buildings, or establishments at which alcoholic beverages are sold for consumption on the premises."
Now you can make the argument that the 2A says I should be able to "bear arms" and does not put any restrictions on it. Fine, but until the lower law is changed, I'm going to abide by it (at least until fighting in the streets is a common occurrence, then a license will not matter).
I would like to see a National Concealed Carry License (NCCL) that trumps any state requirements. The license I envision is free from any of the restrictions stated above, but requires annual proof that the person holding the license is a law-abiding citizen and has a modest proficiency with arms.
A NCCL would go very far to discourage crime and smaller acts of terrorism. The NCCL would virtually eliminate firearms from being used as a weapon of choice by the terrorist cowards. Right now, there is NOTHING to stop them from going to a church on Sunday morning and killing or wounding 100 or more (and probably live to do it again!).
The public at large would have a hard enough time buying off on the NCCL concept, much less an atmosphere that allows everyone to go about armed EVERYWHERE, ALL THE TIME. I just don't think the latter will ever happen.
