Protests are continuing in Ferguson, Missouri, over the police shooting of the unarmed African-American teen Michael Brown. Police say Brown assaulted an officer and tried to reach for his weapon. But witnesses say Brown was shot with his arms up as he tried to flee an officer’s fire. More than 50 people have been arrested in ensuing protests. On Tuesday, around 100 people marched on the St. Louis County Courthouse chanting “hands up, don’t shoot.” Overnight, dozens of protesters were blocked from marching on the street where Brown was shot dead. In a separate incident, police say an officer shot a man who had brandished a handgun. The claim has not been independently verified. The victim was reportedly left in critical condition.
