During Thursday's announcement of a new assault weapons ban, Sen. Dianne Feinstein (D-Calif.) displayed guns as props during her. However, the guns on display break Washington, D.C., gun laws- as reported by CNN. 

Sen. Feinstein got special permission and does not have to abide by the law. 

The D.C. gun ban gained media attention in a weird incident in December, when Meet the Press host David Gregory brandished a high-capacity gun magazine while in the midst of interviewing the National Rifle Association's executive vice president, Wayne LaPierre. Originally intended to prove a point, Gregory's gutsy move not only captured the attention of the national audience, but also landed him at the center of a police investigation.

After the show aired from its Washington, D.C., studio, the Metropolitan Police Department (MPD) opened an investigation concerning the legality of possessing such a magazine within the district.

If charged, it appears that Gregory faces a penalty of up to a $1,000 fine and no more than one-year in prison.
