U-T San Diego:  “One day after the San Diego City Council took up the issue of taxing marijuana, narcotics agents raided one of the last remaining medical pot dispensaries in downtown San Diego Tuesday morning.  The regional Narcotics Task Force also ran a parallel operation to seize pot plants at homes and businesses in North County. About 1,000 plants were seized, according to spokeswoman Amy Roderick of the U.S. Drug Enforcement Administration.  Agents headed out about 10 a.m. and served at least 10 search warrants downtown and in Del Mar, Escondido and Oceanside . . . . the DEA’s goal is to shut down what he called ‘marijuana clubs’ operating in violation of federal law.”
