Why Didn’t We Think Of This Before?

After the shipyard shooting, we have the usual suspects—Nancy Pelosi and Barack Obama among them– crying that we need new gun laws to prevent these senseless mass murders.  But that seems like an indirect and ineffective approach, because we already have thousands of gun laws on the books, and every single one of these cases involves the deliberate breaking of one or more of them, resulting in tragedy.  So why don’t we get directly to the problem, and pass a law against murder?!?  Really, why didn’t we think of this before?
