Did David Gregory have a legal Loophole to be in Possession of that 30 Round Mag

As you might have already heard, David Gregory is being investigated for possessing a 30 rd AR magazine which is banned in D.C.

Jesse brings up a very interesting point in all of this… Washington D.C. may very well have a legal loophole for the film/television industry that would allow him to do what he did. Legally.
