Firearms aren't vehicles
Whenever "concealed carry permits" are brought up in conversation, oftentimes the concept is compared to that of a person with a driver's license; however, they are vastly different in more ways than one. The reason a driver's license works in ANY state in the United States that you travel to is because "states voluntarily recognize each other's driver's licenses" (Everytown).
Though "every state requires a driver's license to drive a car...[there are twelve states that do not] require a permit to carry a concealed handgun in public and 19 states don't require any safety training" (Everytown). This means that if all states were to recognize the lowest/weakest standards present. Quite literally "forcing every state to allow these individuals to carry concealed handguns would be like forcing states to let visitors drive on their highways without a driver's license and without having passed an eye, written, or road test" (Everytown). It just doesn't make sense.
Driver's licenses are also much easier for law enforcement to verify than concealed carry permits. It gets tricky as 12 U.S. states do not even require you to have a permit to carry, meaning if a person who carries in one of those 12 states were to travel to another state, say Illinois, there's no national standard for CCR. The out-of-state resident carrying a firearm cannot necessarily be verified by law enforcement.
"Forcing states to recognize the weak concealed carry laws of other states is dangerous. Recent research shows that, when states weaken their laws about who can carry a concealed gun in public, violent crime rates rise by 13-15%. And a new study in the American Journal of Public Health finds that stronger concealed carry laws are associated with significantly lower rates of firearm homicide" (Everytown).
Though both driver's licenses and concealed carry permits SEEM similar in concept, they are unique to their own motive and need to continue to be respected and understood as such. To imply that a firearm should be treated with the same amount of flexibility as a vehicle is a preposterous notion at best.
The conversation simply isn't apples to apples.
