THE GUIDED CHAOS WEAPONS SERIES, PART 1: KNIFE OFFENSE. From the military to civilians and even the police-- knife, gun and stick fighting is often taught unrealistically. Based on the brutal, bloody, forensic homicide research of former detective John Perkins plus Perkins' over 100 seriously violent arrests, this comprehensive 4 part DVD series separates film fantasy from forensic fact and dojo delusions from real combat.
