So an article about Ghislaine Maxwell argues that she was possibly the victim of a perjury trap. So, of course I looked up what a perjury trap is, and it is where a prosecutor brings someone before a grad jury and asks them questions specifically to get them to lie, then indicts them on perjury.
My question is why is this illegal or frowned upon? If you lie under oath, you, well, lied under oath. Who cares if the prosecutor set you up? You made the decision to violate your oath. What am I missing?
