Chicago is once again the scene of mass protests, this time the result of a video dramatically showing black teenager Laquan McDonald being fatally shot by the police. The officer who shot McDonald 16 times has been charged with first-degree murder.

That hasn’t dampened either the anger in the black community or law enforcement concerns that police officers may be ambushed in retaliation as gang members seek to capitalize on the discord. The demonstrations have mostly been peaceful so far, though sometimes tense. One young protester was filmed staring down police officers, getting right in their faces and occasionally shouting, “Shoot me 16 times!”
