I hope this becomes law. The process here is really cumbersome
Be careful. There are several ways Congress can intervene here, and some of them are bad - in fact, most of them are bad.
1) They could pass a law that every state must recognize every other state's permits. This is probably unconstitutional, since most permits are issued under a state's police power, and there is no general Federal police power.
2) They could create a Federal CCW permit, good in all 50 states and DC. Lawmaking being what it is, this would be as hard to get as the hardest local permits, like NYC or DC.
3) They could make Federal funding for police departments contingent on reciprocity with the 49 other states. This would be the fastest, simplest, and likely most effective method, although I hate this kind of Big Daddy coercion in general.
What they should do immediately is pass DC reciprocity. I was caught up in a flash mob at the National Zoo in 2011, with seven small children, and a guy was stabbed 20 feet away. I wrote immediately upon returning home to FORMER Senator Kelly Ayotte (yay!) asking for DC reciprocity, she wrote back some stupid letter about her budget strategy.
The process in Californicator land makes it basically impossible to get a C&C permit.
