New York City has mandatory three year jail sentences for tourists who attempt to turn in their guns upon seeing a “no guns” sign.
Above is a story detailing the jail term faced by a marine from Indiana, with no criminal record, who turned in his gun at the Empire State building. He did not know his concealed carry permit was not valid in the state.
New York is locking up tourists for not being aware of the strict gun prohibitions in that state.
Make it easy on yourself, Don’t vacation in New York City.
