City court workers in an Atlanta suburb will undergo sensitivity training and post courtroom dress code signs after police arrested a Muslim woman for refusing to remove her headscarf before attending a hearing. A judge ordered Lisa Valentine, 40, to serve 10 days in jail for contempt of court after the Dec. 16 incident. She was released in less than a day. Muslim rights activists have asked the Department of Justice to investigate the incident that triggered a protest in Douglasville, a city of about 20,000 people on Atlanta's suburban outskirts. Council on American-Islamic Relations spokesman Ibrahim Hooper said Wednesday the training doesn't address the problem.
