New Mexico has ruled that officers may confiscate firearms from your vehicle during a traffic stop even if they have no reasonable cause to do so, trampling the 2nd Amendment as well as the 4th. Also in New Mexico (as in many states), if you have a conceal carry permit, you are supposed to announce to the officer that you have a weapon on your person. Meaning, now you have to let the traffic cop know that you have a firearm in the car and hope he doesn’t decide to take it away from you:
I can just see it. Cop pulls you over for an immigration check. You tell them, "I have a concealed weapon." The cop arrests you for threatening a police officer. It goes in the report, "The accused threated me saying, 'I've got a gun, copper!'"
