I have never been in a fight in my life and I have zero experience with what you are talking about but, watching cops this past weekend, they had two situations in a row where the persons "causing a disturbance" were wacked out of their head (supposedly on drugs) and had zero response to pain manipulation and tazers (sp?). They simply gang tackled them and kept calf roping them until they were incapable of not complying. I think it would be difficult to control someone like that by myself.
Interesting topic. Thank you for relating your real world experiences.
