Arkansas state Sen. Jeremy Hutchinson (R) recently learned why a good guy with a gun isn't always the best way to stop a bad guy with a gun.

During an "active shooter" training exercise, Hutchinson accidentally shot a "teacher" with a rubber bullet-loaded pistol rather than the "shooter."

"The tough part is when law enforcement does arrive, it's hard to distinguish between the good guys with guns and the bad guys with guns," Hutchinson told the New York Daily News. "There were gun shots in the hallway, there's a man shooting into the classroom, and I shot that person (with a simulation bullet)."

"At the end of the simulation, the chief said that was a man playing a teacher in the hallway, who was gunning down the (fake) shooter."

Hutchinson is the nephew of former DEA chief Asa Hutchinson, who lead the National Rifle Association's National School Shield Task Force. The NRA task force concluded the best way to protect children from gun violence was to place armed guards in every school. The guards could either be hired security officers or armed teachers.

Hutchinson last year proposed allowing teachers to carry firearms in school. He also supported legislation to allow university staff and faculty members to carry a concealed handgun on campus.

“The ideal would be to have a trained resource officer in every school,” he told the Arkansas Democrat-Gazette. “The state and school districts can’t afford that.”
