Problem is, the Australian model doesn't include the "enshrined in the founding documents of the country" problem that we have. They made the law, and people adhered to it. Badda-boom, badda-bing. In the USA, you would have to alter the Constitution in such a way as to REMOVE a right from all Americans. That ain't gonna fly. Ever. In the end, a dead American can't bring a lawsuit before the Supreme Court. And even if someone did it on their behalf, the individual didn't die because of a gun. They died because someone shot them with a gun. Which is VERY different, legally speaking. And no matter how tragic that individual's death, it does not supersede the constitutionally-enshrined right of 350 million other Americans. It's just not a legally tenable position to take, so there's not point in discussing it.
