By being at the right place at the wrong time, WCBS-TV, CBS's flagship station in New York City, was able to capture an angry melee that erupted Sunday night during a high-school basketball game at Madison Square Garden and spread to the streets. Boasting that it had exclusive coverage of the often bloody brawls involving hundreds of fans, Police, and passersby, the station aired some of the footage on its late-night newscast and posted it on its website later. It reported that 21 arrests had been made but that the number could grow higher when a final count came in today (Monday).
