We will not tolerate violence', says St Louis police chief

St. Louis Police Chief Lawrence O'Toole recaps the incidents of violence on Friday night following the acquittal of a white former policeman accused of murdering a black man.
Activists marched peacefully through a suburban St. Louis-area shopping mall on Saturday, hours after police clashed with a crowd protesting the acquittal of a white former policeman accused of murdering a black man.
In a second day of demonstrations over a judge's ruling in the 2011 case, hundreds of people snaked through the West County Center in the St. Louis suburb of Des Peres, chanting "Shut it down" and waving fists in the air.
Police were out in force but did not tussle with protesters, unlike the previous night, when nine city officers, a county officer and a state trooper were injured and at least 33 people were taken into custody, said St. Louis Police Chief Lawrence O'Toole.
On Friday, Circuit Judge Timothy Wilson acquitted former St. Louis Police Officer Jason Stockley, 36, of first-degree murder in the shooting death of Anthony Lamar Smith, 24.
The verdict comes about three years after rioting broke out in the St. Louis suburb of Ferguson when an unarmed black teenager was shot dead by a white police officer.
That incident touched off a nationwide soul-searching over law enforcement's use of force against African-Americans, the mentally ill and other groups.
After Friday's ruling, some 600 chanting protesters marched from the courthouse through downtown St. Louis, some of them holding "Black Lives Matter" signs.
