 says that you couldn't own a cannon when the Second Amendment was first around, which you could, and ends by failing to say the famous phrase, the tree of liberty is watered with the blood of patriots. Enjoy. I used to be a law, when I was no longer the vice president, I became a professor at the University of Pennsylvania. Before that, I taught a constitutional law class, and so I taught the Second Amendment. There's never been a time that says you can own anything you want.
