Here too, every inch of school property is a drug, tobacco and alcohol free zone. We have signs at every entrance of the parking lot. It applies to everyone: students, parents, visitors, staff etc. The drug dog makes random visits and I think a random visit means they check every lot equally and not just the student or visitor lots because that would be considered a double standard.
As a teacher; she knew better... and I would guess there's a clause in her contract. Unless it was an amount that suggests dealing, it would just be a civil citation-like a ticket - and not be a criminal act or have a criminal penalty. But yes, she will probably lose her job and it will place a big dent in her career. I have to say, if she taught my kids, I would support her termination. Rules are rules.
Hardcore, I know. But alcohol AND cigs are legal and it applies to those as well. Though I am not sure a drug dog can detect either in closed car!
