The Justice Department will determine whether officers with the Portland Police Bureau use excessive force, especially against mentally ill subjects.
The probe will determine whether there was a "pattern or practice" of excessive force. Assistant U.S. Attorney General Thomas Perez of the DOJ's Civil Rights Division announced the probe Wednesday.
Marva Davis, whose son Aaron Campbell was fatally shot by Portland police in January 2010, and James P. Chasse, whose son James Chasse Jr. died in police custody in September 2006, were among those who attended the news conference, reports The Oregonian.
This year, the DOJ has begun or conducted civil rights probes of departments in Seattle and New Orleans.
