Phoenix New Times:  “Yavapai County Attorney Sheila Polk announced in dramatic fashion last July that federal authorities would shut down every medical-marijuana dispensary in Arizona ‘as it opens.’  Polk made the bad prediction in a letter she penned and sent to the governor after getting several other county attorneys to sign it. We checked into her assertion and reported to you at the time that Polk’s claim appeared to be nonsense and was, in fact, a major exaggeration of something she’d been told by a retired drug agent.  How wrong was Polk’s info?  As of today, there are 16 retail shops legally selling medical marijuana under Arizona law.”
