Who Should be Responsible for Bar Fights that Hurt Others?

Multiple lawsuits have been filed against hip-hop artists Chris Brown and Drake for starting the massive bar fight that resulted in injuries to numerous bar patrons, who needed emergency treatment, stitches, and other treatment from glass-related injuries.  Because the members of each entourage got involved, an ordinary bar fight turned into a massive brawl in which 300+ lb. 6’5″ men were  “throwing highball glasses laden with alcohol, shattering the handles of bottles of spirits to use as makeshift knives and even throwing full bottles at each other.” Within seconds, the club was “full of flying glass shrapnel.”
