Unfortunate for sure. Sounds like a kid with that condition may have been in the wrong type of school,but at 6, it was probably early on in the process before she would be moved to some kind of special needs or alternative school.

If it was a medical condition, why would she be sent to the office for discipline? What good would that do?

In my experience, you never see resource officers at the elementary level, I'm assuming he was called in from a local middle or high school. Could they not get in touch with the parents or guardians instead to come deal with it? I give no apologies for the kids actions but it sounds like the AP escalated things because she wanted to press charges because of a kick.
