The use of mace by security guards inside Sumner High School on Tuesday has students upset and school officials investigating.
The early indication we've been told by St Louis City Schools is that the guards did everything right in breaking up a big fight in the cafeteria involving close to a dozen students.
Furthermore we're told the guards have been carrying the mace for some time and have used before.
Yet the burning spray has some burning over whether it's right to use it in school.
It's worth noting that no one was serious hurt although at least three were taken to the hospital and the rest were treated at the scene.
