On May 15, 2012, Oklahoma Governor Mary Fallin signed Senate Bill 1733, an amendment to the Oklahoma Self Defense Act, which will allow people with Oklahoma concealed weapons permits to open carry if they so choose. The law took effect November 1, 2012. "Under the measure, businesses may continue to prohibit firearms to be carried on their premises. SB 1733 prohibits carrying firearms on properties owned or leased by the city, state or federal government, at corrections facilities, in schools or college campuses, liquor stores and at sports arenas during sporting events."
