I don't believe that ANY "physical" maneuvers or "techniques" are really worth teaching children. An EIGHT year old vs. a GROWN adult who is most likely a violent psychopath with a HISTORY of violent criminal behavior?
I can't see it.Instead, emphasize the following:1. RUNNING at the FIRST sign of trouble. IMMEDIATELY and in a "zig zag" pattern and using the environment as a "hedge".2. SCREAMING as LOUDLY and HYSTERICALLY as possible.3. Wriggle, twist, turn, jump......ANYTHING to make the potent.
