Re: Principles of pinning
You see multiple police officers trying to subdue a resisting suspect frequently. A part of that was already mentioned in that having additional officers often reduces the chance of the suspect or arresting officer from being injured. A well-trained officer can usually restrain a resisting suspect by himself, but if additional help is present, why take the chance? The comedian Ron White tells a story about being thrown out of a NYC bar one evening by five bouncers. He said he didn't know how many it was going to take to kick his ass, but he knew how many they were going to use.
