Conservatives clamor for the states to be restored to their historic roles defining marriage and regulating abortion. So why the clamor here for a federal rule that will allow state law restrictions on the concealed carrying of firearms in public to be swept away? Shouldn't each state be allowed to make its own decisions about a matter so consequential to the safety of its citizenry?
If full faith and credit can be given to a Marriage License, a driver's license, why not a concealed carry permit?
It involves a course of instruction, and a test to be passed before issuance in those jurisdictions which have one. In those which do not require a permit to carry concealed, proof of residence should be sufficient.
Because those criteria vary, and because it is practically impossible for those not politically connected to acquire one in some jurisdictions, there is an absolute hodge-podge of rules, which can and have ensnared the unwary with felony charges out of ignorance, for crossing a line on a piece of paper, getting off at the wrong exit, or any of a number of misfortunes.
Criteria for the use of deadly force also vary, and those can be a trap for the unwary. Some states set the bar for the use of lethal force lower than others, and using the criteria fro one of those states in one where use is limited to dealing with a imminent threat of serious injury or death can land you in prison.
At the least this opens the issue to discussion.
