Why would you want to stop someone who's on your side? Isn't that a bit like the Germans saying "Stop the Vichy French?"
Oh, and those 1.4 million prohibited persons you say your prior restraint edict stopped? Back when I almost got arrested for asking Sarah Brady and Jane Harman about that, it was only touted as 100,000. Anyway, each attempt by a prohibited person to buy a firearm is a violation of federal law, so if you guys really knew what you were talking about instead of grabbing numbers out of your...uh...the air and lying to everyone, we'd see that many arrests and prosecutions, right?
