That's the truth. I went to s particularly safe middle school, so when we had a random weapons sweep with metal detectors, only 3 students got caught. I was one of them; I had my little 1" swiss army knife, one girl had a steel nail file with a sharp point, and a mexican kid had a 3" folding buck knife.

Me and the girl were white honor students, and we were let off with a stern warning, and our "weapons" were handed to our parents. The mexican kid with poor english skills got sent to an alternative school (the kind for disciplinary risk kids).
