O'FALLON, Mo. (AP) — The white St. Louis couple who became internationally famous for standing guard with guns outside their mansion during a protest have pulled a gun before in defense of their property, according to an affidavit in an ongoing case. As demonstrators marched near the Renaissance palazzo-style home of Mark and Patricia McCloskey on Sunday, video posted online showed him wielding a long-barreled gun and her with a small handgun. The protesters, estimated at around 500 racially mixed people, were passing the house on the way to the nearby home of Mayor Lyda Krewson.
