Been to a school lately?
Been a teacher in an inner city high school in Miami, FL for nine of the last seventeen years. No big deal. Happens all the time. My school had a fight a couple days ago and one side showed up with a baseball bat and then the other side pulled a knife. Security handled it, no cops were in on the action.
I've known teachers who have been jumped and beaten badly...even critically. In all my years I have never been seriously threatened. There are a couple of reasons for that. First I usually start the year off right...by showing them my military photo album. Second, I tutor the football team after school so they can graduate. Anybody who messes with me gets an off campus visit (in da HOOD) from the offensive line.
ONCE in another school near the one where I currently teach I had to step into a fight where a young female teacher was being threatened. Thereafter the Principal asked me very politely to notify security so they could avoid a lawsuit from defensive actions I might take in the future. In this case, there was no impact on me in any way. However when I transferred schools to the one where I am currently in an even more ummmm challenging environment.....(deeper inner city) that story seemed to precede me somehow....
