It’s never the wrongdoing -- it’s the lying about it. Pennsylvania Attorney General Kathleen Kane, who announced her resignation Tuesday in the face of a possible 14-year sentence for her conviction on perjury charges, proves the truth of that adage for public corruption cases. Leaking grand jury proceedings to embarrass a political rival would not have gotten her sent to prison. But lying about it under oath could and will.

How could a state’s top law enforcement official be so dumb? Why are perjury charges so serious? And why don’t people, even lawyers, realize it?
