He meant well! Via the Palm Beach Post:
A school district employee participating in armed "guardian" certification accidentally shot themselves at the Palm Beach County Sheriff's Office gun range on Monday, June 10, according to the Palm Beach County School District and sheriff's office.
The civilian employee, whose name is being withheld in accordance with state law that prohibits identifying safe school officers, is in stable condition following the shooting, according to a school district spokesperson. The person's injuries were characterized as non life-threatening.
District-operated schools in Palm Beach County do not arm teachers or staff. Instead, the school district has its own police force, which stations an armed officer at every campus.
