I know you're shocked to learn the two terrorists who blew up the Boston Marathon did not register their guns as required by Massachussetts law. You know, the guns they used to kill an MIT police officer and engage police in multiple gun battles.
In fact, the younger terrorist wasn't even of legal age to own a handgun.
Oh, and when it doesn't fit the anti-gun agenda, the term "assault rifle" is no longer used. But the Muslim terrorist brothers had one. Reuters simply called it a rifle and the liberal Mother Jones called it an M4 carbine - both accurate terms, indicentally. But all we've heard since Newtown is "assault rifle." And did their handguns have "high capacity magazines?" Haven't heard about that one yet.
I'm sure it's just an honest mistake on the part of the media.
