Even Chris Rock says in his stand-up routine, "if Ammo cost $5 grand there would be no more innocent by-standers".
If ammo cost $5 grand, then only the 1% would own weapons because they would be the only ones who could afford to buy the ammo. Ones ability to make money doesn't always reflect their intelligence or skills. Look at Honey Boo Boo and the Kardashians...
But, for Christ's sake, even you have to admit that a lot of dumb asses who barely tell time get handguns.
Do you propose an intelligence test to get a firearm license?
I'll be honest with you. I would support a state issued firearm license. Training and a background check are required to obtain the license. If you served in the military and you pass the background check, you can have a license. Once you obtain the license though you no longer have to pass a background check to purchase a firearm or ammo. You show your license and as long as it is valid, you are good to go. You could also have different levels of licenses based on training/proof of certification. All state licenses would be valid in other states for the possession of your firearms, but you would only be allowed to purchase firearms from the state you have your license in.
I'm not sure how we integrate mental health checks into the background check system. The professionals who help people would be the first line of defense but they themselves have to be cautious in their use of reporting people. Lives can be ruined if not used properly. No bias in their reporting either way. Families can play a part but once again we have to be cautious and have due diligence when families are involved. Spouses going through divorce can cause problems for each other in the false reporting of crimes to get back at one another. Making it so a law biding spouse looses their right to a firearm based on the word of an ex could become a common thing and our rights are to be protected above all else.
Those who are convicted of committing a crime with a firearm get an automatic 10 year sentence for having the firearm, on top of the sentence for the crime you committed.
