It never ends. Legal Insurrection notes that Washington D.C. prosecutors have declined to charge David Gregory, an NBC bobble-head, for illegal possession of a 30-round magazine. The evidence for the crime is uncontroverted--Gregory appeared on national television with the magazine. The explanation given was that Gregory was using the magazine to further his First Amendment rights and no violation was intended. (But it is illegal to possess one to further your Second Amendment rights).
The real reason for the decision, of course, is Gregory is an important person--a friend of the D.C. Attorney General, apparently.
