A firearms instructor hired as a security guard at a Michigan charter school after the deadly Newtown shooting left an unattended gun in a restroom at the school.

Last week, Matt Young and Bill Kraly, co-directors of Chatfield School in Lapeer, Mich. Announced they were hiring retired Lapeer County Sheriff's Dept. firearms instructor Clark Arnold as a security guard.

But this week, they admitted he had left an unloaded gun in one of the school's restrooms.

"The school has put additional security procedures in place that follow local law enforcement practices and guidelines," said Young in a statement. "At no time was any student involved in this breach of protocol. We will continue to work on improving school security."

No word on how school officials found out about the gun, or whether any students knew it was there.

But no charges are likely because no one was harmed.

"If you left a gun unattended and a toddler finds it and shoots and hurts someone, it could be some kind of reckless use of a firearm," said Lapeer County Prosecutor Byron Konschuh.

But since no one was hurt, "it's almost like no harm no foul," he added.

Konschuh elaborated, "There are charges such as reckless use of a weapon, possessing a weapon in an area where you're not supposed to, having an unlicensed weapon and all kinds of weapons offenses, but I can't think of one where this fits under any of those definitions," he said.

Still, he seems to understand everyone lucked out in this situation.

"It's not beyond the imagination that an elementary school child could have picked up the gun and walked out in the hallway. Now they're standing there with an unloaded gun - what happens then?"

Apparently nothing, as long as no one gets shot.
