If you're thinking of shopping at Whole Foods, don't. According to Zoe Marks, a witness , a black man who tried it in Oakland was beaten unconscious: In Oakland less than four hours and I just saw a young man violently assaulted by an armed security guard at Whole Foods - slammed repeatedly against concrete pillars, put in a chokehold, restrained, and suffocated until he was thrown face down on the pavement unconscious.
