Researchers have asked teachers: What do you think?
Nearly three-quarters (73 percent) of U.S. educators said they oppose the idea of arming teachers and staff in school buildings, according to a Gallup survey in March of 497 adults who teach students from kindergarten through the 12th grade.
More than 80 percent said they would not train to be able to wield a firearm if their school presented the option to do so.
The unpopularity of the idea of arming teachers among teachers themselves suggests that lawmakers who support the idea will face difficulty implementing it, even if such policies came to pass.
"Nobody can force teachers to carry guns," said Frank Newport, editor-in-chief of Gallup, a global research firm. "Teachers would have to agree."
More than half of teachers say arming staff members would make schools more dangerous. Just this week, a California teacher's gun accidentally went off in class and three students were injured.
However, 20 percent of teachers support the idea of arming staff members and 18 percent would undergo special training to carry a firearm at school.
"They tend to be teachers in rural areas who already own guns," Newport said.
Teachers who feel they'll be able to protect their students with a firearm should be given the chance to, said Dave Workman, of the Second Amendment Foundation.
"In the event of some tragedy like we saw in Florida, they want to jump between the bad guy and the good kids," Workman said.
