I watched the video.  The deputies appeared calm.  I'm not sure how to deal with a situation where you have a non-compliant inmate. The deputies did not beat him nor were they responding out of anger.  I can't say if they used excessive force because I don't know what that is.  It is easy to take issue with law enforcement, and there have been many questionable incidents publicized over the last few years, but in a situation like this what would you do?
