In my experience, most subjects sprayed with OC are significantly impaired. Of course, we need to train for that percentage upon whom OC has little or no effect.
We adopted the two spray recommendation after several years experience with OC. In adopting this protocol, we referred to a 1994 study conducted by the Portland (ME) PD which seemed consistent with our experience. This study examined 226 OC deployments by Portland officers.
Portland reported an average of 1.2 sprays was required to control a suspect (one burst in 182 incidents, two bursts in thirty-nine). There were six incidents in which a subject was hit with more than two bursts. In five of these cases, the spray was still ineffective. It's out belief that, if you've hit the subject twice without effect, the spray will probably not work on this particular occasion.
Portland officers considered OC effective 85% of the time. If one eliminates mechanical problems with the canister, possible misses, medical cases, and incidents in which officers could or did not give OC time to work, the success rate would be 97%. Whichever percentage (if either) one accepts, there are still a percentage of people who will need to be taken down by other means.
It's also part of our training that OC is not a replacement for the baton, the taser, the firearm, or the flashlight. Be safe.
