The "Universal background check" debate is such a manipulative sub-topic of gun control, a real "foot in the door" type argument if you will. The very nature of the question sounds to an uninformed person like this, "Hey, it only makes sense to do background checks right? It'll keep the bad guys from guns".
What they don't understand that outside of a locally controlled registration region (Hawaii for example), in the free states that don't have mandatory registration laws, this "universal background check" legislation is absolutely 100% unenforceable. If this federal law drops in the books on 1 Jan 2014, and I buy a gun from my buddy on 2 Jan 2014; who is to say that the transaction did not occur on 31 Dec 2013? or 2010 for that matter? This whole thing is just setting the groundwork for the greater goal of initiating a federal level registration process, now much easier to justify as a way to close the "date loophole" I just described. But of course they will wait till the next madman shooting to role that nugget out.
It is poorly planned, feel good legislation at its finest, championed by knee jerk politicians who are planning to ride the coat-tails of tragedy all the way to the ballot box. Makes me sick...
