right. The argument that you can;t change things because there are so many guns out there is defeatist and stupid. It took generations to get where we are, it doesn't matter how long it takes to fix it - you still have to start moving in the right direction. Guns get old, they rust, they get confiscated, people who find them in attics will turn them if there is a bounty etc., etc. The gov can mandate change in ammo sizes to obsolete all the old ones. There are any number of things that can be done. Just get off zero.
