You will be arrested if you use a
weapon to defend yourself.
My father a left handed shoemaker was held up at gunpoint and when the perp reached over to the register while watching my fathers right hand my father cut him across the back of the neck with his left hand. He took a knife to a gun fight and won and the police wanted to lock him up for using excessive force but the local store owners prevented it from happening.
This is common that's why no-one will assist you in NYC. The only friendly people in the city are transplants.
