So you are contending that crime increased because of the assault ban? Nope. Not buying it. As far as the Second Amendment goes, show me a shred of evidence where there has been legislation to repeal it. Constitutional provisions aren't necessarily meant to exist unfettered or unrestricted. First Amendment rights are challenged all the time. We have freedom of speech, but, if you for instance were to threaten the President of the United States, it is a felony. This is a common sense restriction to free speech, not an attack on it. In other words you can't just say anything you want. There might be consequences. Restrictions exist, rightfully, in a civilized society.
"Threatening the President of the United States is a class D felony under United States Code Title 18, Section 871. It consists of knowingly and willfully mailing or otherwise making "any threat to take the life of, to kidnap, or to inflict bodily harm upon the President of the United States"
