Tony Pirone, the former BART police officer who took part in the exchange which ended with Oscar Grant’s killing on a train platform on New Years Day 2009, lost his case to get reinstated into his old job. An arbitrator upheld Pirone’s 2010 firing, the San Francisco Chronicle reported

Pirone, who kneed and shouted racial epithets at Grant in the moments before Grant was killed, fought to be reinstated in his old job. BART fired Pirone for his conduct the night Grant was killed.
