In a one-page letter to John Minnis, director of the Oregon Department of Public Safety, Standards and Training, Giusto said he questions whether Green continues to meet the standard for "good moral fitness," based on his conduct in 2004.

A criminal investigation showed that Green stopped several women inappropriately in 2004 and asked them to lift their shifts, remove their bra or unzip their pants, pretending he was looking for a suspect who had a flower tattoo. When questioned about his actions, Green lied to a supervisor, the inquiry showed. In March 2005, the Multnomah County district attorney's office found it would have probable cause to charge him with coercion and official misconduct, but prosecutors did not believe they had evidence to prove the charges beyond a reasonable doubt.

A sheriff's internal investigation found Green inappropriately stopped at least 10 women. He was disciplined with an unpaid suspension of an unknown period and returned to patrol eight months ago. When Green's case became public, Giusto transferred Green to the training division this month. On Monday, Giusto placed him on paid leave after District Attorney Michael Schrunk sent Giusto a letter saying he won't use Green as a witness in any court proceedings. The district attorney's office has also reopened a criminal investigation into the deputy's conduct.
