NBC News and David Gregory's non-prosecution
A ways back, NBC's David Gregory appeared on Meet the Press, filmed in DC, flashing around a 30-round AR-15 magazine, in public violation of DC's ban on such. DC was pressed to prosecute and, of course, declined. Legal Insurrection blog sought to obtain, via the Freedom of Information Act, data relating to the non-prosecution, and won another motion, to obtain a police affidavit that called for his prosecution.
Also at the link are emails between NBC News and the DC Police Department, before the event. NBC asks, can we bring in and show the magazine? DC PD responds no, it is completely illegal, just use a photo of it.
The only thing more ridiculous than criminalizing possession of a box and spring is refusing to enforce the ban based upon the possessor's clout and friends.
