KTVB-TV reports today a key new detail about this week’s accidental shooting on the Idaho State University campus: 20 students were present when the instructor, who has an enhanced concealed carry permit, accidentally shot himself in the foot in a chemistry classroom on the campus. The male instructor had a loaded handgun concealed in his pants pocket, the station reports; it went off while he was teaching. KTVB’s full report is online here. Idaho lawmakers this year passed legislation allowing people with those permits to carry concealed guns on Idaho public college and university campuses – over the objections of every one of the state’s public colleges and universities, and at the urging of the National Rifle Association.
