Catch 22 law?
You can own a gun, with permission, but you can’t transport the gun outside your home.
How did you ever get the gun to your home?
Does Amazon/UPS/US Mail etc. have the right to transport the gun to you?
Can you have the gun picked up and delivered to where you will be target shooting?
This really sound like if you owned a weapon before they banned transport of weapons, the weapon can stay with you, but any attempt to use the weapon outside of your home is criminal.
I used to live in NJ and would have a shotgun in my truck all the time in case I wanted to swing by the trap range after work. Then they changed the law (30 years ago??) that you could only have a gun in your car going to or from the range or hunting. (Not sure about concealed carry at that time - I only had long guns back then.)
That's it.
The law also ignores the “bear” clause (bear claws ... get it?), which forbids the government from infringing upon the right to CARRY arms.
