Retired Montana Principal John Moffatt says arming teachers and school staff is not the right way to respond to the threat of school shootings. His opinion is informed by his own experience as the survivor of a 1986 school shooting at Fergus High School in Lewistown, Mont., where a student gunman shot Moffatt in the abdomen after shooting and killing a substitute teacher. Teachers around the country have organized to oppose similar bills, which lawmakers introduce perennially to address public concerns about school safety. Supporters of such bills say they give willing educators another option to protect their students.
