From Ron Gatewood:
Targets!!
This is a chart I prepared when I taught the California Highway Patrol for the straight baton training
Consider the minimal damage to Rodney King with 50 some strikes. One or two strikes with a straight baton (especially rattan) would do far more damage if used properly.
PS: I still have the complete PR-24 training manual that was issued to me to earn my certification which I plan to put on e-bay but if someone is interested let me know before I post it, I will list it soon.
