Seeing as how she confessed to committing perjury, I would say yes. People have been put to death based upon confessions, I'd think a perjury charge would be a slam dunk.
So mob rule gets to decide who does get thrown under the bus when no crime is committed as well as decide who doesn't get prosocuted despite a confession to committing a felony? Is that really the world you want to live in? Besides, it just doesn't play out in reality. The mob didn't get what they wanted. All I want is simply the rule of law to be enforced, why are you of all people against that? You are generally a much more rational person, certainly we can't provide incentive to perjuring yourself in front of a GJ or jury can we? What possible good can come from that? Not to mention the fat cat banksters that got away with the exact same thin in front of friggen Congress no less, why is that ok? Why do YOU tolerate it?
The main reason I'd say prosecute her is because she broke the law, period. Is that not something that reasonable people can agree upon? If not, why do we have the rule of law at all? Should I be able to commit perjury against you in a court of law? If I did and it lead to an unfavorable outcome for you, would you want me prosecuted or would you be saying the same thing?
