Cell phone video shows a 15-year-old black girl being beaten to the ground by 4 other black teens inside a Brooklyn McDonald’s as dozens watched and cheered. The savage fight broke out inside a McDonald’s on Flatbush Avenue near Erasmus Hall High School this Monday afternoon (3/9/2015). The girl in blue swings at one of the teens but is soon outnumbered by her target’s friends. The 4 relentlessly pummel the girl, who continues trying to throw punches
