Give him a raise and a promotion.
I wouldn’t provide any more security or help to any school. They need to just start suspending kids left and right. Five days here, ten days there...make them repeat entire class years after 20-odd days of suspension in one year. Cops don’t need to be involved. Schools need to dump that kid (no matter what age they pretend to be) back onto the parents. If you got some punk loser kid who just can’t pay attention in class....well, McDonalds doesn’t require a high school diploma and that punk can be the fries guy or the burger flipper.
Save real cops for real work. School security isn’t worth the cost or effort.
