In order to secure a warrant a law enforcement official must submit a sworn statement attesting to the facts that justify the warrant. If the sworn statement is false, the law officer is guilty of perjury. Not only that, but the entire case would likely be thrown out of court.
Do you have any examples of charges being brought for perjury on a wiretap, arrest, or any other type of warrant?
I get the case being put in jeopardy, I’m not looking for examples of that. I’m looking for an example of an investigator or prosecutor being charged with a crime — not being sued for civil damages, but indicted by a prosecutor.
