DOUGLASVILLE, Georgia — The Douglasville Police Department said Monday its officers will undergo “sensitivity and cultural diversity training” after a Muslim woman who refused to remove her head scarf at a courthouse was jailed. “We never want this to happen again. It’s not our intent to embarrass anybody,” Police Chief Joe Whisenant said at a news conference. The judge who had the woman jailed briefly for contempt of court will also take part in the training, Whisenant said.
