I'm not gonna comment on the above argument/discussion, all has been said...but I have experienced something like that
My Middle School in 7th grade was the worse school in the county...as in bad kids, trouble makers, drugs, weapons, fighting, etc. We had metal detectors and what not, but anyways, yea, there's one thing I remember clearly.
A weapon and drugs "dropbox" right outside of the Gym, it was in order for kids who 'might' have incriminating and illegal things to place them in that box so they won't inadverdently harm or make trouble in school...funny thing was, there was a camera right on it. I remember kids were stupid enough to use it, any kid caught on camera was punished lol, regardless if the illegal item was there's or not, and regardless of race.
Maybe under school or district rules, that if you possess a firearm on schoolgrounds, you get expelled. In this kids case, he possessed the weapon, although in a short time, he did. Seems like those people are more of hardasses on policy, rather than racist. Thats just how I see it...
I still think the school's decision is bullshit...if that junk was a real gun...well yea...not gonna think beyond that.
