Michael Taylor believed in second chances — he was living proof that they come along. Before the early 1990s, the Los Angeles resident had been an addict, a dealer, eventually homeless. But one day he decided to turn his life around, and achieved the miracle — sobered up, straightened out and found his legitimate passions: community activism and radio. He became a reporter and later an occasional host of public affairs programming on Pacifica station KPFK. So he was a felt presence among Los Angeles’ South-Central community of leftists and grassroots organizers at the time of his cold-blooded murder over nothing more than a low-power radio transmitter, in April 1996.
