“Elizabeth Elderli never leaves her Houston home unarmed. So, when the former U.S. Marine visited Manhattan's September 11 Memorial, two guns were in her backpack when she saw a “no firearms” sign at the security checkpoint. Elderli told a police officer about the loaded 9-mm. and .380-caliber semi-automatic guns — both covered by her Texas-issued concealed weapons permit, which she believed was valid in New York. But she quickly learned that the Empire State's gun control laws bear no resemblance to those in effect back home. Elderli was arrested in the Saturday incident, charged with felony possession of a weapon and left facing 3 ½ to 15 years in prison.”
