“ST. LOUIS — A white couple who stood outside their St. Louis mansion and pointed guns at protesters who were marching toward the mayor’s home to demand her resignation support the Black Lives Matter movement and don’t want to become heroes to those who oppose the cause, their attorney said Monday. Video posted online showed Mark McCloskey, 63, and his 61-year-old wife, Patricia, standing outside their Renaissance palazzo-style home Sunday night in the city’s well-to-do Central West End neighborhood. He could be heard yelling while holding a long-barreled gun. His wife stood next to him with a handgun.”
