There are two big lies going around in the wake of the Parkland school shooting last week. They are the same two big lies that go around every time one of these tragic events occurs. The first is that we can keep this from happening again just by passing a few laws about guns. We can't. The idea that people who want to break laws will find ways to get guns to break laws is not entirely wrong. Legislation is a blunt instrument not a magic wand.
