But instead of focusing limited federal resources on off-the-grid growers in places like Humboldt County, who are often armed and violent, Haag targeted Matthew Cohen, a medical-marijuana farmer in Mendocino who was growing 99 plants under the direct supervision of the county sheriff. As part of a pioneering collaboration with local law enforcement, Cohen marked each of his plants with county-supplied tags, had his secured facility inspected and distributed the mari*juana he grew directly to patients in his nonprofit collective.
Cohen appeared to be precisely the kind of caregiver that the Ogden memo advised should be given safe harbor for operating in "clear and unambiguous compliance with existing state law." But last October, DEA agents stormed Cohen's farm in the middle of the night and cut down his crop. Sheriff Tom Allman, who learned of the raid on his turf only an hour before it was executed, was outraged. "Matt Cohen was not in violation of any state or local ordinances when federal agents arrived at his location," Allman says. In January, Haag took the fight to the next level, threatening county officials like Allman with federal sanctions. Three weeks later, county supervisors voted to abandon the program to license and monitor Mendocino's legal growers. "This is a huge step backward," says Allman.
