It will be interesting to see how this is handled, if he is prosecuted, what consequences are applied.
If it is found that he did not do anything wrong, or given a slap on the wrist and back to the classroom, or full pension retirement then I will be calling this a made up fraud by the left and their teachers union.
Slam him into oblivion because if he gets off the hook then we all know left lying and fraud is what this is all about.
Possessing and discharging a firearm on school grounds is a serious offense likely not overlooked.
