Unfortunately the "Gun Control" advocates make the unconstitutional assumption that all gun owners are potential criminals. Just read their amici briefs in any 2nd amendment case. Their position is based on guilty until proven innocent. This is the unconstitutional part. Based on this false premise they seek to suppress all 2nd amendment rights. They continue to hold the "collective right" theory of the 2nd Amendment. That position is now dead as a result of Heller. But the gun control side will never yield.
The best source of information on the subject is in the Heller, McDonald, Masciandro, Woollard, & now Gowder cases. The amici briefs are chocked full of this junk. If you read the Woollard thread on this site you'll find that the statistics regarding gun violence are biased in order to prove the position of whatever side paid for the research. If you read judge Legg's rulings you'll find that he doesn't find any compelling arguments for either side. He also found that it doesn't matter, the 2nd Amendment is NOT a permission from government. It is a pre-existing right protected from the government.
The correct debate to have is whether as a society we want to pursue a Constitutional Convention for the sole purpose of repealing the 2nd Amendment. I don't believe it would succeed at convention. However, if it did I don't expect it would succeed when put before the people. This is what the Supreme Court found in Heller. That the Supreme Court could NOT overrule the will of the people (as one of the dissenting justices wanted to do). The people have already ratified the 2nd amendment intentionally guaranteeing it as a right of the individual, not a collective right of the state. There are no collective rights anywhere in the Constitution. There is no Bill of Collective Rights.
Good Luck with your personal crusade.
