Port Arthur Massacre

I've been debating on posting about this since we visited the Port Arthur Historic Site because it is a very sensitive issue in Port Arthur. They even request that you not ask questions about it to the staff, but instead refer to a pamphlet they make available. I finally decided to post it to provide for you the information I had access to at the historic site.
This page is an online version of the pamphlet. I will let you read it for yourself. Instead, I want to take this in a slightly different direction. Rather than the past, let's look at the future: this event directly resulted in some of the world's strictest gun control laws, as well as a 'buy back' period for guns currently owned by citizens.
The Second Amendment is passionately defended by many Americans, and honestly, I am not prepared to argue against it. After ten years however, on September 13, 2004, the Federal Assault Weapons Ban was allowed to expire without renewal, and I can think of no justification for this inaction.
