Even trained martial artists get fooled by the four D's,
because they do not appear on their training curriculum.
Therefore, they do not understand the enemy that they are
facing and so also fail to grasp -and therefore translate -
'street speak', the mass deception often causing
disorientation. The attacker uses the former and latter to
prime a victim that is only trained in 'physical response'. As I
have already stated, deceptive dialogue is the professional
attacker's leading technique. Understanding this will allow
you greater awareness, it will keep you 'switched on'. Being
switched on to all of the forgoing is the better part of 'Target
Hardening'.
