We don't know exactly what happened in the Mullica Township kindergarten class where two students went into a bathroom and may have taken their clothes off.

But neither does anyone else - except two 5-year-olds.

What we do know is that on Sept. 30, teacher Kelly Mascio discovered that a boy and girl had slipped into the classroom bathroom without her knowledge. Each told her the other wanted to "have sex." We know that Mascio reported the incident promptly.

The children later told investigators that they had taken off their clothes and touched each other. Mascio had allegedly not been told by school administrators that one of the students had been involved in a similar incident the previous year.

The 16-year veteran teacher was suspended with pay after the September incident. This week the district filed tenure charges against Mascio, a step toward trying to fire her, and she is no longer being paid.

Based on what we know, that seems a gross overreaction. Mascio's suspension and any efforts to fire her seem to be a reaction to the disturbing specter of kindergartners undressing and talking about having sex, rather than a response to any action on Mascio's part.

Let's be clear. The impulse to protect young children from sexual crimes should be paramount in any school, and incidents between students have to be taken seriously.

But some of those incidents are simply normal curiosity. And the threat of lawsuits sometimes creates an incentive for administrators and districts to take extreme measures, to allow an attitude of zero tolerance to supplant good judgment.

School officials said Mascio was suspended for failing to properly supervise her students.

So ask yourself this: If the incident had involved two students who had been unsupervised long enough to draw crayon pictures on the walls or knock over a lamp, would the teacher have been disciplined in any way?

The children had gone into the bathroom while a movie was being shown, on a day when students were moving in and out of the classroom for testing. Police and investigators from the state Department of Children and Families who were called to the school found no reason to file criminal charges or pursue a broader investigation.

We don't know what the kindergartners were thinking or how they heard the term "have sex." When young children act out sexually it can be a sign of something more serious. Or it can be as innocent as repeating something they overheard from older children or, unfortunately, a television show.

But how does any of that reflect on Mascio?

If school authorities believe Mascio's supervision of her class was inadequate, why jump to trying to revoke tenure? Why not follow the usual disciplinary channels?

Until we learn more about this case, anything more than that smacks of an overreaction.
