Pissed Off Student Urinates in Teacher’s Coffee

I have to wonder what this teacher did to deserve this...

Yes, a 16 year old student got so upset that he went and tainted the personal coffee pot in that his teachers drink out of. I imagine his grudge was only with one teacher, but several ended up consuming the "homemade" blend. One teacher said it tasted like chemicals while another required medical attention. Yikes...

What I find odd about this story is that the teenager is facing assault charges. Seems a little extreme for peeing in the coffee. Don't get me wrong, I want to see him punished, I just don't understand how he assaulted anyone. Mainly, the teachers were concerned about the health risks of consuming urine, which I suppose is fair.
