Bail is set at $520,000 for Jeff Joseph, owner of a popular Venice-area dispensary. His attorney says the prosecution is politically motivated and disputes the D.A.'s claim that state law bans sales. More than four months ago, Los Angeles County Dist. Atty. Steve Cooley warned that state law does not allow dispensaries to sell medical marijuana and zeroed in on Organica, a popular Venice-area outlet, as one possible target.
