And Mother Jones magazine has revealed a well-known activist in the gun control movement is actually a secret spy for the National Rifle Association and the gun lobby. Over the past decade, the woman, Mary Lou Sapone, managed to become active in almost every single major gun violence prevention organization. Sapone, who went by her maiden name Mary McFate, helped organize the Million Mom March in 2000 and oversaw the lobbying efforts of States United to Prevent Gun Violence. Mother Jones reports Sapone has a history of spying on activists. During the 1980s, Sapone infiltrated the animal rights community while working as an operative for a Connecticut-based security firm.
