FERGUSON, Mo. — A couple hundred defiant protesters remained in Ferguson early Sunday morning after a midnight curfew took effect in a St. Louis suburb where a black teen had been shot by a white police officer while walking down the street. Hundreds of other protesters left peacefully before the midnight to 5 a.m. deadline took effect in Ferguson, Missouri.Remaining protesters mingled, chanted and taunted police, some shouting that they would not abide the curfew. Some stood with their hands up, the emblematic pose used by many protesters to characterize the position witness have said 18-year-old Michael Brown had assumed when he was fatally shot.Police dressed in riot gear kept their distance.Gov. Jay Nixon on Saturday had declared a state of emergency in Ferguson. As the curfew approached late Saturday night, New Black Panther Party leader Malik Shabazz roamed the street with a bullhorn, encouraging people to leave for their own safety. Many appeared to follow his suggestion.“C’mon you all, let’s roll out,” Shabazz said through his bullhorn. “Let’s roll out of here, get some rest and come back tomorrow.”Crowds that were in the hundreds prior to the curfew had dwindled significantly in the final hour.Despite heavy rainfall and lightning, hundreds of protesters gathered Saturday night at a busy thoroughfare that has been the site of previous clashes with police. Scores of officers, a much more visible presence than the night before, stood watch — including some with shields.
