PCP, also known as "Angel Dust," is an illegal substance whose abusers become savagely insane, temporarily gain superhuman strength (strong enough that often, a half dozen burly, fully-trained law enforcement people are unable to restrain them), and are impervious to pain. So-called "bath salts," which have similar effects (except supposedly even stronger) are now being cited in the recent case of the naked man who bit off another man's face in Miami, Florida before being shot dead by police.
Do you think most wulin martial artists could restrain someone on PCP without killing that person? I figure someone with Greats-level martial arts could do so easily, but what about people more at the Mo Brothers or Yeung Hong level?
