An American police officer has been shot in Ferguson, Missouri, as anti-racial protests continue over the death of unarmed African-American teenager Michael Brown. Brian Schellman, a spokesman for the St. Louis County Police Department, said the incident occurred on Saturday night and that the officer was a woman. The officer was shot in the arm and expected to recover. The suspect fled the scene of the shooting near West Florissant Avenue and Stein Street. People in Ferguson have been in the streets since the police killing of 18-year-old Brown on August 9. Ferguson police chief Thomas Jackson issued an apology to the family of Brown on Thursday. "I want to say this to the Brown family. No one who has not experienced the loss of a child can understand what you are feeling," Jackson said. "I am truly sorry for the loss of your son." However, Brown’s parents have rejected the Ferguson police chief’s apology. His mother, Lesley McSpadden, demanded Jackson’s ouster, while his father, Michael Brown Sr., called for the arrest of white police officer Darren Wilson, who shot their son. "An apology would be when Darren Wilson has handcuffs, processed and charged with murder," Brown Sr. said. Activists want prosecutors to charge Wilson with murder, although he has continued his job on paid administrative leave. Wilson has spoken with investigators and testified before a grand jury, who is still considering his case. The US Department of Justice and the FBI are continuing to investigate the incident for civil rights violations. In a speech on Saturday night, President Barack Obama urged black leaders and law enforcement to build trust over racial issues. “Too many men of color feel targeted by law enforcement ... and the mistrust scars the heart of our children,” he said. “It’s not the society our children deserve. Whether you’re black or white, you don’t want that from America.”
