Being an NRA member and a NRA Range Safety Officer, I have come up with a sure fire solution to the many problems in the US right now with everyone owning or wanting to own firearms.
1. Allow every firearm ever made to be owned.
2. Own as many as you would like.
3. Outlaw all reloading equipment and supplies.
4. Each person may purchase 1 bullet at a time.
5. With each bullet purchased you must trade in a spent cartridge of the same caliber/type.
6. You must also give up 100 brain cells with each purchase.
After the first bullet purchase and trade in of spent cartridge and brain cells MOST gun owners won't have enough brain cells left for a second purchase.
