There are enough blatent flaws in the arguement above to show that this is someone who has *zero* knowledge concerning guns, American firearm laws, and gun crime.
He's talking about the AFT(sic, I assume ATF), suggesting "lesser" caliburs for hunting firearms when most assault rifles are of lesser calibur (5.56mm, 9mm, etc.). He suggests we register guns when we have been doing that since before I was born. He suggests stiffer penalties for crimes committed with a handgun, which we already have. He suggests making it illegal to sell guns to people in their 20's, though they are legally recognized as adults.
And not a single suggestion that would have prevented the case he is talking about. Not unlike most people who erupt every time there is a shooting, as though no one is ever killed any other way...
The fact is most Americans, and most people in other countries, unless they are interested in guns, have no clue what the laws are where they live. I have talked to people in other nations that were SURE it was illegal to own a gun, and upon checking I found their nation's laws about as lax, and in some cases even more lax, than ours.
