St. Paul civil rights leaders are demanding an officer who allegedly maced an 85-year-old man be fired. They also want the federal Department of Justice to investigate possible civil rights violations. The demands stem from the arrest last week of Leon Nins as he was taking food to his wife in a nursing home. Officer Michael Lee pulled Nins over for a traffic violation. Nins then says Lee handcuffed him, used a chemical irritant and beat him on the legs and arms with his baton. Friends of Nins' from his church and his family stood by him at a press conference today. His son, Thomas Nins, a Baptist pastor from Connecticut, says he can't understand how his father posed any threat that warranted the officer's reaction.
