PORTLAND -- A U.S. Department of Justice investigation concluded that the Portland Police Bureau engages in "a pattern and practice of excessive use of force," specifically when dealing with the mentally ill, U.S. Attorney Amanda Marshall announced Thursday.
The investigation found such use of force violates the U.S. Constitution. Still, she said, the problems revealed in the probe are not unique to Portland and the vast majority of PPB's use of force falls within constitutional limits.
The investigation was launched in June, 2011 to examine the use of deadly force against all citizens, with a specific look at the mentally ill.
The PPB had a "high number of officer-involved shootings, especially those involving people with mental illness," Assistant Attorney General for the Civil Rights Division Thomas E. Perez explained at a press conference Thursday.
The findings revealed that too often Tasers and other uses of force were used when they were not necessary, Perez said.
He said training deficiencies within the department helped lead to the civil rights issues, and department has wasted no time in beginning the process of improving.

The investigation followed several controversial police shootings, including the death of Aaron Campbell. The January 2010 incident sparked protests and one officer was fired for his use of deadly force.
Another high-profile case was the death of James Chasse, who died in PPB custody after an encounter with police in Old Town in September 2006. Officers said Chasse appeared to be urinating outdoors and when he tried to get away they tackled him. His autopsy revealed that Chasse suffered 26 rib fractures and a punctured lung.
Investigators said they would look for systemic problems within the PPB and would also meet with community leaders outside of the bureau.
A press conference was scheduled for 10:30 a.m.
