"New York courts have interpreted "proper cause" as having a "special need for self-protection" as compared to the general population."
Article is misleading. The courts have determined that other uses also constitute proper cause. These included hunting, fishing, camping, sport, target, etc.
Unfortunately for Westchester residents, other neighboring county residents are free to carry a concealed weapon in Westchester county. So if you live there you can't carry while surrounding county residents are carrying in your county. This fact renders the judges opinions on the subject moot.
