Just in case you missed the news. Alger Hiss and Harry Dexter White were guilty. Julius Rosenberg was a spy and deserved to die for treason as revealed by Kruschev and the declassified Venona papers. Sacco and Vanzetti, executed in 1927, were guilty according to their fanatic supporter Upton Sinclair. Poor Roger Coleman, executed in 1992, turns out to have failed his second and most recent DNA test.
Our system is based on the demand that all innocent and guilty criminals plead innocent in 
order to get a trial and free lawyers who will try their cases in the press if the press is interested. Criminals with lefty political leanings get the extra benefit of becoming martyrs.
I hope my readers understand that not all judicial systems in the world work this way.
I was a stupid gullible fool for most of my life. I believed that Julius Rosenberg, Nicola Sacco and Bartolomeo Vanzetti were unjustifiably executed.
