even if it were to pass you think states like NJ would follow it?
No. NJ wants it's own citizens to be totally defenseless. You can bet they won't tolerate people from other states toting guns around.
It's almost funny. The only LEGAL means of self defense here in Lautenbourg, other than your bare hands, are guns. The degree of difficulty in obtaining a gun permit varies from inconvenient, to downright impossible, depending on the police chief of your town. If he wants his people gunless, he sites "Insufficient reason to issue" as the excuse for turning down your permit application. That's it. Your only option is to move to another town, and try again. Or, move to Pennsylvania. America starts there. Any other type of weapon is illegal, and the POSESSION of most are felonies, like slingshots, for example.
Here's the list of illegal weapons, again. Slingshots, knives with blades > 3", batons, Tasers, blackjacks, billies, nunchuchas, brass knuckles, throwing stars, pepper spray, crossbows and mace. If you are a disabled hunter, and get documentation from your Dr., you can get a crossbow permit. Permits are also required for airguns and muzzleloaders. These would be the very same permits you need for firearms.
Now, if we can only figure out a way to regulate sticks and stones.
