We haven't had any teachers carted away but unfortunately there have been quite a few such incidents with the students this year.
When I was teaching this happened three times. One guy was selling drugs out of his classroom. One was molesting some of his male students. One was a substitute who passed out in the classroom just before lunch. It turned out the big drink cup she had been hitting on all morning contained straight vodka on ice. I guess she mis-judged her capacity. She couldn't handle 48 ounces before lunch.
