Has banning drugs made them more difficult to get? Here's a newsflash, Sparky: CRIMINALS DON'T CARE ABOUT LAWS. Rational gun laws don't take guns out of the hands of law abiding citizens.
You can pass all the leftislation you want, "assault weapons" and hand guns aren't going away. They'll still be manufactured in other countries, bought by criminals, and traded all around the world because they're basically used as currency. The only thing you ignorant morons will be successful in is eliminating another thing we actually manufacture competitively in the United States.
