Well, I started this thread, and although it has wandered off into the ditch a couple of times, I appreciate every one's comments.

I have been working on some workplace violence related issues, more on the risk management side and less on the personal survival side, but I see a couple of common denominators:

-The goblins are usually "tough guys" in the mirror before they leave to do their dirty deed, but out on the field, they turn rather cowardly and avoid conflict. (That is why my 2 daughters, school teachers with strict protocols to follow, each know where the closest fire extinguishers are to their class rooms, because a control freak shooter will most often walk away from uncontrolled situations like my crazy kids with fire extinguishers! I also followed the advice of a random email blast that said in lieu of pepper spray, a good blast of wasp spray to the eyes will rock a goblins world, while not drawing attention like pepper spray would.
