Recently my hometown, Louisville KY, made the national news for a large number of teenagers, some estimate over 200, running wild on the waterfront and downtown. 3 people were hospitalized from various assaults that were part of this incident. Some of these assaults involved over a dozen attackers at one time. Most of my training has involved 1-3 attackers in one general area. Do you have any recommendations on how to defend yourself against such a large number of attackers?
