I wear a sweatshirt quite often and any almost everytime I put any of my handguns in the pouch they hang down and pull the opening open far enough that the gun can be seen. With that in mind I don't carry that way.Most sweatshirts have a deep pouch in front to keep your hands in.
so either this cop has x-ray vision, or the idiot had the gun hanging half out of the pouch.
But, in reality, it's what @spat said. Arrested for perfectly legal behavior in America.
Think of what the victims might say.Headline should read "NY state troopers arrest man for something that isn't a crime in most of rest of the US."
