Here's a curiosity. Mother Jones has a piece about a woman named Mary Lou Sapone, who infiltrated various gun control lobbies on behalf of the National Rifle Association under the name Mary McFate. She also appears to have employed her daughter in law in a similar role.
A resume that Montgomery Sapone used around 1999 describes her role within Mary Lou's business: "Collect and analyze intelligence on European activities of major international environmental organization for a company specializing in domestic and internal opposition research, special investigations, issues management and threat assessment. Write weekly intelligence update on European animal rights and eco-terrorist activity. Assist in confidential litigation support research."
…Sapone made her gun control work a family affair as well. Around 2003, Montgomery volunteered at the Brady Campaign, according to Becca Knox, the group's research director. Occasionally, Montgomery would also sit in for her mother-in-law at Washington strategy meetings attended by officials of the gun control movement, according to the Violence Policy Center's Kristen Rand.
(via) Montgomery McFate, as she is now known, is one of the authors of the US military’s human terrain programme in Iraq and Afghanistan. She also helped write the US army’s counterinsurgency field manual. So she continues to work on gun control issues. Funny old world.
