Thousands take to the streets in Chicago

CHICAGO (AP) — Thousands of protesters are marching through the streets near Chicago's City Hall, blocking traffic and chanting, "16 shots and a cover-up!"

Today's march is the latest in several weeks of protests after the release of video showing a white police officer shooting a black teenager 16 times in October 2014.

The video showing 17-year-old Laquan McDonald's death also has led to the forced resignation of the city's police chief and multiple investigations, including a pending civil rights inquiry by the U.S. Justice Department.

The crowd, which set out from Daley Plaza in the early afternoon, was peaceful but angry.

Retired teacher Audrey Davis says Mayor Rahm Emanuel's speech promising reform was "politically expedient."

She says she doesn't want to hear anything from him except "I tender my resignation."

Meanwhile, two alderman support Emanuel's address to the City Council, saying that the McDonald video was key to sparking calls for police reform.
