CHICAGO (CBS) — The state’s largest teachers’ union is pledging to fight any attempt to allow teachers to carry guns in the classroom.

Illinois Education Association spokesman Charles McBarron said Tuesday that no “sane” person wants teachers packing heat in class.

“The idea that somehow a school can become more safe by bringing more weapons into it is a ludicrous notion,” he said. “It’s hard to believe anyone would say that and mean it.”

Even Illinois State Rifle Association Executive Director Richard Pearson denied saying teachers should be armed, although he told Newsradio he believes that every school should have armed security, and believes that would have deterred Friday’s attack.

Bills are alive in Ohio, Oklahoma and Alabama that would allow more guns into schools. McBarron said if one surfaces in Illinois, IEA will fight it.
