A number of people showed up to the board of supervisors meeting Tuesday to express concerns that former DA Tom Sneddon committed felonies in his prosecution of pop star Michael Jackson in 2005, allegedly misusing his power to pursue a conviction on the molestation charges. An online petition has begun, and the group is asking for a full investigation be conducted by an independent special prosecutor. Jackson, who for a time lived at his Neverland Ranch in the Santa Ynez Valley, died in 2009.
