Koon was acquitted in the Simi Valley beating trial back in 1992 -- and the acquittal triggered the L.A. riots. He was later convicted in federal court of civil rights violations and served 30 months in prison.
Stacey Koon -- the former LAPD sergeant who did prison time for zapping Rodney King with a taser -- has changed careers -- he's now driving a limo.
An independent photog got Koon driving a limo for Music Express, the high-end private transport company. Koon, who was leaving LAX, scoffed at the photog, who asked if he had a reaction to Rodney King's death.
The beating occurred nearly 22 years ago. So we gotta ask.
