In the name of thorough reporting, host David Gregory held up what he said was a "magazine for ammunition that carries 30 bullets" while interviewing NRA CEO Wayne LaPierre on Sunday's edition of Meet the Press. Turns out, that's actually illegal in D.C.

According to NPR, D.C.'s official code states that: "No person in the District shall possess, sell, or transfer any large capacity ammunition feeding device regardless of whether the device is attached to a firearm." And police are already on it.

As of this morning, the Metropolitan Police Department confirmed to the Washington Post that they are "investigating the matter."

Granted, Gregory was asking LaPierre whether high-capacity ammunition magazines should be banned. So maybe that's his defense?
