This kind of ploy

is only useful in the
very early stages of the attacker's ritual and only if the locale
is right. If you have been abducted or are completely
detached from the herd it could be dangerous. Many
attackers kill their victims if they think that they have been
recognised. In all these cases your intention is to frighten the
adversary, via your portrayal, into bottling it. The common.
street term for this process is 'Psyching Out' .
Climbing inside the opponent and switching on/off his fight
or flight reaction to beat him with guile, as opposed to force,
is advanced play and needs a great understanding to employ
with conviction. Practice is of the essence if you want it to
work and not backfire on you. I go into greater detail on the
subject in my autobiographical books about my ten years as a
nightclub doorman Watch My Back - A Bouncers Story,
Bouncer and On The Door -Further Bouncer Adventures.
