CHICAGO: Small groups of demonstrators gathered again Wednesday to protest the death of a black teen shot by a white police officer, and they urged supporters to join them in trying to shut down Chicago’s famous Michigan Avenue shopping district during the Black Friday shopping bonanza.

About two dozen protesters gathered outside Mayor Rahm Emanuel’s office a day after authorities released a graphic squad-car video showing the officer firing an entire magazine into 17-year-old Laquan McDonald. Jason Van Dyke was charged Tuesday with first-degree murder.

The group held banners showing photos of other black people fatally shot by police in Chicago and elsewhere. Several protesters said they were parents of black men killed by Chicago officers.

“You cannot kill our children and expect us to be quiet any longer,” protester Quovadis Green said. “It is unacceptable.”

Activist Mark Carter called on people to “rise up” and shut down the Magnificent Mile shopping area on Friday. Protesters also planned to target the Board of Trade and other landmarks in the coming days, he said.

Carter and others want the Department of Justice to investigate the Chicago Police Department and its history of covering up bad behavior.

The Urban League of Chicago joined in the call for a federal investigation, alleging a pattern of “discriminatory harassment” against black people.

The Rev. Jesse Jackson said other officers involved in McDonald’s death should be fired or at least suspended. He also wants a special prosecutor appointed to the case, complaining that Cook County State’s Attorney Anita Alvarez took too long to bring a murder charge in the shooting, which happened more than a year ago.

President Barack Obama said Wednesday night he was “deeply disturbed” by the video footage.

Obama said in a Facebook post that he is asking Americans to “keep those who’ve suffered tragic loss in our thoughts and prayers” this Thanksgiving “and to be thankful for the overwhelming majority of men and women in uniform who protect our communities with honor.”

Obama said he is personally grateful to the people of his hometown — Chicago — for keeping protests peaceful.

Democratic presidential candidate Hillary Rodham Clinton also weighed in, saying McDonald’s family and Chicago residents “deserve justice and accountability.”

Clinton, who made the comments Wednesday in an emailed statement, added that police officers across the country are doing their duty honorably “without resorting to unnecessary force.”

One of Clinton’s rivals, Sen. Bernie Sanders, said in his own statement that all Americans “should be sickened” by the video.

For months, Chicago leaders had feared that the release of the video could provoke the kind of turmoil that rocked cities such as Baltimore and Ferguson, Mo., after young black men were slain by police or died in police custody.

Van Dyke was the subject of 18 civilian complaints over 14 years, including allegations that he used racial epithets and excessive force, police and court records show.

Van Dyke’s lawyer, Daniel Herbert, did not return a message left Wednesday by The Associated Press.
