On a February day 15 years ago Paul Bradford took himself to a local emergency room. Bradford felt agitated and confused; he and his wife thought he needed professional help. To his surprise, two large men came into the waiting room, grabbed him by the arms and hustled him into a treatment room. Petrified, Bradford asked his wife to stay with him, but he says the security guards forced her out, tied him to a gurney and gave him a sedative that knocked him out for 18 hours. He awoke in a locked ward, where he was kept for more than two weeks.
