(New York, NY) -- The New York man who became known as the "subway vigilante" in the 1980s is in trouble with the law for allegedly selling marijuana to an undercover officer. Bernhard Goetz gained notoriety after he shot four black teenagers on a New York subway car in 1984. He was acquitted of murder and assault charges, but was convicted of illegal possession of a weapon. He served less than nine months in jail. Police say Goetz was arrested Friday night after he sold marijuana to a female undercover officer.
