I was going to say the same thing Clint Keller did, but he got there first. Guns won't magically disappear if they're outlawed, and they won't stop being made and sold and owned. The only thing that will change will be who's doing the making and the selling, and possibly the owning. The crime rate won't go down, because criminals aren't usually concerned with where their guns come from or if they're legal. Another niche for organized crime to fill.
