If you are pulled over, they generally don’t have the right to search the vehicle. Do gun owners have to disclose that they have a weapon in the car after a traffic stop, and does the existence of a weapon by someone who has a permit grounds to seize and search the weapon for excess bullets? If so, it would seem to eliminate the 4th amendment for gun owners.
I have not been pulled over in a long long time but I do know that they will observe the interior of your car for suspicious items. It seems to me that if they want to find some pretense to go further they will. Especially the state troopers.
As far as firearms go I do not have a carry permit. They are not easy to get. I have not needed one. When I travel to my friends house to use my shotgun I keep it in the trunk with the shells in the car.
I live in westen N.J. & we are different from the rest of the state. We have a gun culture here & local police do not bother us. We shoot on my friends property. Noone bothers us
because gunfire is a common occurance.
