In last week's column, I talked about how our school system is just like any other segment of society. It contains people geared for success and others who are geared for as little as possible.This being the case, I think it's time for teachers to be drug tested, just like every other segment of society. There's no reason for teachers to have a Captain America shield that keeps them in a protective bubble.Since we published the story about a fifth-grade teacher getting arrested at school for buying drugs in the parking lot, the overwhelming question I've been asked is "Why aren't teachers drug tested?"Many people from all different professions have approached me and brought up the fact they are drug tested at work.
