I heard about this on the radio yesterday, and the radio station had a bunch of listeners call in. Some were outraged, some said she deserved it. However, one lady who was a member of the school board said something like "parents now expect the school to take care of their children, and if the smoking problem is not fixed, the school could be liable for not taking action". I was like WTF? And then I realized: most people are as sheep as they come, and they want the school to take responsibility for their children, yet are outraged when they punish them, and so the schools come back with the ploy that they are just going to punish all or none...Stupid stupid stupid. Its a vicious circle.
My stance on this: she should not have been suspended unless she was caught actually smoking on campus. Circumstantial evidence, last I checked, is still not good enough to convict in a court of law; it should be no different on school campuses.
