Pennsylvania has an MOU between prosecutors, law enforcement, and other interested parties which bans law enforcement from requiring victims to submit to a polygraph examination or other form of truth-telling device as a sole condition for proceeding with investigation or prosecution.
Vermont has an MOU between the Office of Attorney General, the Department of State's Attorneys and Sheriff's Association, and the Department of Public Safety and the Chiefs of Police Association which bans law enforcement agencies from requiring victims of crime to submit to a polygraph examination or other form of truth-telling device as a condition for proceeding with investigation or prosecution. A victim may voluntarily take such a test if the victim is advised that he or she is under no obligation to do so. Case investigation and prosecution may not be terminated based on victim refusal to undergo such a test. Investigators and prosecutors should take all other possible investigative steps before asking a victim to undergo testing.
