From the NYC DA's office press release:
District Attorney Brown said that, according to the charges, Meckler presented a locked gun box to a Delta Airlines ticket agent at approximately 5:20 a.m. this morning, December 15, 2011, during check-in. It is alleged that the box contained a Glock 27 pistol and nineteen 9mm cartridges. Meckler, who has been in New York since Sunday, December 11, 2011, allegedly told authorities that he had the pistol because he gets threats and that he does not have a New York State carry permit.
FOPA does not cover an extended stay in NYC since he was not traveling from the 11th to the 15th. I truly believe that this man is in serious trouble and will be lucky to avoid jail time and even more lucky to keep his right to practice law anywhere in this nation. If he did this on purpose, wow, really a dumb move in my opinion.
