Vancouver, Canada when bars were forced to shut down at 2am, resulted in thousands of drunks pouring into the streets all at once and mass brawling with each other. Laws were changed to allow 4am last call and legal after hours, and the gigantic street brawls disappeared. A barwatch association was started to keep out chronic violent offenders and known gangsters from clubs and bars too which helped.

There's also juiced up goofs here running around one punching random people while their friends film their crime and yell "worldstar" (worldstar hiphop) which is the site where all the recent knockout game idiocy originated.
