90% Rule - ASP techniques are designed to work 90% of the time in 90% of the situations that officers face. However, nothing works 100% of the time. Officers should not give up a good technique because of an exceptional case in which a procedure does not work. In the same manner, officers must always be in a position to disengage or escalate if a procedure is not effective.
