I've heard the 18 shootings thing too. My wife told me someone posted about it on facebook, and I said, "I call bullshit. Source?"

I saw a video on youtube the other day about MD confiscating 30-round magazines, and telling everyone they had "x" amount of days to turn them in before it became illegal to possess them. 

One of my favorite conversations is with people that want to ban "black" rifles, or guns in general. We are not Australia, there is no way in hell we could successfully and safely remove the firearms currently in the market even if it wasn't a terrible idea. And turning in your own firearms to prevent gun crime is like giving yourself a vasectomy because your neighbors are having too many kids.
