NY has had the sullivan law for almost a 100 years now.It's fairly well known that you are gonna get some significant Jail time for carrying without a permit in NY.What Burress got was a plea deal, would have been longer if convicted at a trial.Here is a link on sullivan law.Interesting list of people who have or had permits.

Current and past New York City license holders include:
Senator Charles Schumer
Don Imus
Harvey Keitel
Joseph Bruno
Ronald Lauder
Edgar Bronfman, Sr.
Howard Stern
Donald Trump
William F. Buckley Jr.
Joan Rivers
Arthur Hays Sulzberger
Robert DeNiro
It may be on the harsh side and its constitutionality may come into question with some recent rulings from supreme court but Burress really had no buisness carrying a piece IMO and should have been aware of where he was and what the laws were.
