The Press-Enterprise:  “Two top Riverside officials are asking U.S. attorneys to enforce the federal marijuana ban in their city, as the feds have in other Southern California communities during a recent crackdown on medical marijuana operations. . . . In October, the state’s four U.S. attorneys began a crackdown they described as targeting commercial distribution of marijuana.  Dispensaries in French Valley and Wildomar have been shut down in recent months, others in the Inland area have received warning letters, and federal officials have filed civil and criminal actions against dispensary operators and property owners who rent to them.”
