Doesn't suprise me at all...and stuff like this is but one of the many things that pissed me off about school. The regular troublemakers, bullies, juvienile deliquents and outright thugsintraining never got punished* in the slightest for their continuous offenses while if you were one of the good students that behaved they would come down on you hard for everything.
*Well except when they tried to *expletive deleted*ck with rednecks like me, we kicked the *expletive deleted*it out of them...because hell we were going to get suspended anyway for daring to be the victim of an attack, we figured might as well get even
