Any pupil who is convicted or adjudicated delinquent for possession of a firearm or a crime while armed with a firearm or found knowingly in possession of a firearm on any school property, on any school bus, or at a school-sponsored function shall be immediately removed from the school's regular education program pending a hearing to remove the pupil from the regular education program for a period of not less than one calendar year subject to modification on a case-by-case basis by the chief school administrator.
From reading that, there is a clear overreach by the school officials. Have the pupils been convicted or adjudicated? No. Was there any school sponsorship of the off-campus activity? No. Sue them!!! Sue them into bankruptcy!
