All joking aside, the main issue here is a state's right to know who has a gun in their state. This is issue seems to have been brushed off repeatedly in this thread. New York knowing who has concealed guns is in no way infringing on a person's right to carry that concealed gun. However, if you get a license in new Jersey and cross in New York, how does New York know you have the weapon? Or are allowed to carry the weapon? They don't.
Sadly, I think that's the main point for many of you pro-gun people. You want to carry concealed and want no one, not even the state, to know about it.
Regardless, as has been mentioned, this is DOA in the Senate.
