The District of Columbia is no stranger to civil disobedience, to protesters who break the law to make a point. But never have the protests involved more than 2,000 loaded rifles. So you can understand the anxiety many are feeling after activist and radio host Adam Kokesh — best known in these parts for dancing at the Jefferson Memorial — announced his “Open Carry March,” a protest against government “tyranny” featuring gun-toting protesters marching across the Memorial Bridge into D.C. And you can understand the even greater anxiety after Police Chief Cathy Lanier said Tuesday there’s a “pretty good chance” her officers will meet the protesters on the bridge. “If you’re coming here to protest government policy, great,” she said on NewsChannel 8. “If you’re coming here to break the law, we’ll take action.”
