Source: Justice Department to investigate Chicago Police

CHICAGO (AP) — The U.S. Justice Department is expected to launch a wide-ranging investigation this week into the patterns and practices of the Chicago Police Department similar to recent probes of Baltimore and Ferguson, Missouri, after a white Chicago police officer shot a black teenager 16 times, a person familiar with the matter told The Associated Press on Sunday.

White officer Jason Van Dyke was charged with first-degree murder more than a year after the killing and just one day before the release of police dashboard camera video showing the officer firing 16 shots at the black teenager.

[...] Emanuel forced Police Superintendent Garry McCarthy to resign and formed a task force to examine the department in an effort to calm the city and deal with the most serious crisis of his administration.

In March, the department released a scathing report of the Ferguson police force that found pervasive civil rights abuses, and in May, it reached a settlement with Cleveland police that called for sweeping improvements — including to that department's use of force policies.
