Have you ever dealt with someone on PCP? A few years back, an officer in San Jose CA, shot a man with a knife on PCP, 5 times and the man ended up killing the cop and walking away. He died about an hour later. I personally was involved in trying to restrain a 5 foot, 95 pound white man, high on PCP at the Santa Clara County Jail one night and it ended up taking 7 of us to get him fully restrained.  During the incident, we could tell that one arm was broken in multiple places but he continued to fight us very violently, not feeling any pain apparently. Once we were able to get him under control, the EMT's that responded found that his right arm was broken in three places. Did not stop or slow him down him in any way. Now tell me how that compares to someone being drunk?
