“Based on news accounts circulating that allege federal law enforcement detained two protesters without probable cause, I have requested the Department of Homeland Security Office of the Inspector General to open a separate investigation directed specifically at the actions of DHS personnel,” Williams said in his statement…

In his statement, Williams said federal officers have spent the past 50 nights in Portland defending the Mark O. Hatfield federal courthouse and other federal property. That building has seen significant graffiti, and been a frequent gathering place for protesters opposing police violence.

“[Federal officers] have rebuffed efforts to enter the building by force and have been met with an onslaught of commercial fireworks, laser strikes, glass, mortars, paint and anything else near at hand,” Williams said. “They have endeavored to find the individuals within the crowd who are committing these violent acts and arrest them in a manner that is safe for both the officers and nearby non-violent protesters.”

However, Williams said in “limited instances” federal officers may have engaged in questionable conduct, such as the unmarked vehicle arrests, and that he believes investigations by the Department of Justice Office of the Inspector General are appropriate.
