Never underestimate the power of a deceptively-edited hidden camera video to bring down an organization that tries to help poor people. Despite being cleared by the Brooklyn DA this month, ACORN announced today that it's closing all its offices by April 1st. "For Acorn as a national organization, our vindication on the facts doesn’t necessarily pay the bills," says Bertha Lewis, chief executive of Acorn. Congress voted to cut off all grants to the organization in the wake of videos made by a young Conservative gadfly who, joined by a woman posing as a prostitute, posed as a pimp seeking advice from ACORN employees. The DA found no criminality, but by then the ACORN offices in New York had already reorganized as Communities for Change.
