Even one on one street fights would have sent many more to get medical care unless they're all a bunch of wimps.
The report seems overblown as to there having been that much real fighting.
There were reports that gang members came to the high school during the fight. When local gangs are better armed than LAPD, all "
street fights," especially involving "hundreds... up to a thousand" are relevant.
It's only overblown if you haven't heard automatic gun fire and cross-fire on your street on a Friday, Saturday and Sunday evening.
