Proponents of the bill argue that a permit to carry a concealed weapon is similar to a driver’s license and should be recognized nationwide. But that’s cooked-up logic. States observe similar traffic laws and training requirements before issuing driver’s licenses. That’s not so with guns. In fact, a dozen states put no restrictions at all on who gets to carry a concealed firearm so long as people meet minimal federal qualifications for being able to buy a gun. Other states should not be forced to live under such loose rules if they don’t believe those rules to be safe. Gun owners from Arizona, where no permit is required for carrying a concealed weapon, should not be allowed to wander armed into a state such as California, which has some of the strictest gun controls in the country, without meetings its requirements.
