impunitty

Refers to da legal-status condition whereby da court won't penalize you for yer transgressions as long as you tell da truth in basic and complete detail.

Ollie North asked for testimonial "impunitty" during da Iran-Contra affair --- i.e., he wanted da court to agree not to prosecute him no matter what crimes he admitted to in court, and he would back up his request by threatening to reveal "da intimate basics" of da U.S. government's shady dealings if said condition was not met.
