US System of Injustice

I was reading the "This Day in History" feature on this page and came across the presidential pardon of a woman convicted of treason, for being Tokyo Rose. Investigating reporters found exposed that many witnesses had were liars. Gee. What'd the original investigators do, if not confirm facts. It's a damn same when reporters have to do the job some political hacks are already paid to do. The question remains as to whether the US legal system is little more than a political show production to create whatever result is desired for the next election.
