Justice Department Plans Civil Rights Probe into Ferguson PD

The Justice Department is planning to announce a broad civil rights investigation into the enforcement practices of the Ferguson, Missouri, police department in the wake of the fatal shooting of Michael Brown, law enforcement sources told ABC News.

The sources familiar with the planned probe said it will examine stops and arrests by the department to determine if there has been a pattern and practice of discriminating against minorities. It's expected to be announced Thursday.

The investigation will also examine past allegations of excessive force to determine if there has been routine abuse. This broad investigation will run parallel to the specific probe of Brown's death.
