This is the story of two Marys. Both are in their early 60s, heavyset, with curly reddish hair. But for years they have worked on opposite ends of the same issues. Mary McFate is an advocate of environmental causes and a prominent activist within the gun control movement. For more than a decade, she volunteered for various gun violence prevention organizations, serving on the boards of anti-gun outfits, helping state groups coordinate their activities, lobbying in Washington for gun control legislation, and regularly attending strategy and organizing meetings.
Mary Lou Sapone, by contrast, is a self-described "research consultant," who for decades has covertly infiltrated citizens groups for private security firms hired by corporations that are targeted by activist campaigns. For some time, Sapone also worked for the National Rifle Association.
But these two Marys share a lot in common—a Mother Jones investigation has found that McFate and Sapone are, in fact, the same person. And this discovery has caused the leaders of gun violence prevention organizations to conclude that for years they have been penetrated—at the highest levels—by the NRA or other pro-gun parties. "It raises the question," says Paul Helmke, the president of the Brady Campaign to Prevent Gun Violence, "of what did she find out and what did they want her to find out."
Using her maiden name, McFate, Sapone began posing as a gun control activist in the mid-1990s. Bryan Miller, the executive director of Ceasefire New Jersey, a grassroots gun control group, recalls first meeting her in the summer of 1998. The NRA was holding its annual convention in downtown Philadelphia, and the event drew the usual bevy of protesters. Among them was a middle-aged woman then living in Pennsylvania who made a point of introducing herself to Miller. In the following years, Miller would remember this encounter well, as he watched McFate rise from a street protester to a figure known nationally within his movement. She became a leader of Pennsylvanians Against Handgun Violence and later a board member of Ceasefire Pennsylvania. According to staffers at several gun violence prevention groups, she worked on the Million Mom March in 2000, when hundreds of thousands of people demonstrated in Washington, DC, to demand stricter gun laws. She joined the board of Freedom States Alliance, a network of nine state-based gun control organizations. At States United to Prevent Gun Violence, a nationwide coalition of anti-gun groups, she was the director of federal legislation, an unpaid position that placed her in charge of the outfit's lobbying efforts in Washington. In that role, she collaborated with national organizations including the Brady Campaign and the Violence Policy Center.
