There are things a Private Investigator is allowed to do that citizens are not allowed to do. However, a PI cannot hold himself out to be something he is not, such as a police officer, judge, or parole officer. In a recent case, a Sacramento private investigator was seeking information in a child custody case and used old pieces of identification from his previous job as a parole officer to obtain such information. He reportedly covered the portion of his identification that stated it was no longer valid to trick his informants. He now faces misdemeanor charges for impersonating a peace officer.
