Teachers and students do not assault each other. Period. Any that do should be subject to severe penalties.
"On Oct. 5, 2007, at another notorious middle school, I was deliberately body-slammed on the head by two to three large young men in a P.E. class of 53 students, while another teacher (someone I had never met before) was decent enough to give a formal declaration to school and police authorities of what he had witnessed. I sustained a concussion and sciatica nerve damage as a result of this personal attack intended to 'terrorize [me].' I have memory lapses and continued head and leg pain. I'm told by the local police that this sort of physical abuse on teachers occurs with disturbing regularity. The LAUSD case nurse assigned to my case labeled my attack 'boys will be boys.'" she wrote.
If true, heads should roll--and I don't say that lightly.
