PROF. JACOBSON: The importance of prosecuting David Gregory if he violated D.C.’s gun law.

Certainly, if LaPierre had shown up with that magazine, there would be howls of gotcha, and widespread media demands for prosecution. Why should NBC News and its star be above the law?

There’s another lesson here.

Gregory’s possible violation of the law was exposed by the conservative blogosphere, which also pointed out that Gregory sends his kids to a school with armed security at the same time he was mocking the NRA suggestion of armed security in schools.

We have to do more of this, investigating the investigators and inquiring of the inquisitors. It’s one of the legal insurrections for 2013.

Make them live up to their own book of rules.
