I am in a position this year to dole out punishment to kids. We have a handbook to follow. As I was looking through the handbook I saw some ridiculously severe punishment for certain offenses. I re-wrote that part of the handbook and put a qualifying statement in there that "the following offenses and consequences would serve as a guide but the final decision would be at the discretion of the principal (me)."
For instance, the consequence for tobacco use was three days suspension, automatic. I live in a very rural area with very rural kids. It is getting so that fewer and fewer dip tobacco but I still have a substantial number of kids for whom this is a normal activity. I can see one of my students forgetting she had a dip in her mouth before coming on campus. I'm not sending her home for three days for that. She's probably among my best behaved kids and likely my valedictorian. But I am of the mind for stiffer and stiffer consequences for repeat offenders.
