Town which permits marijuana grows now subject to criminal investigation

The tiny town of Isleton is charing $25,000.00 a month for a permit to allow Delta Allied Growers to operate a 4,000 square foot grow operation.  Now, Sacramento County has subpoenaed the entire city government to the grand jury to talk about that, in preparation for criminal charges against the city.  Contra Costa County had previously threatened the same thing against Oakland, and this sounds like a dry run.
