..actually, Israel convicted him..but after ten years of fighting the conviction, they said there spoliation of evidence and then the mystery eye-witness came forward who claimed he remembers seeing some ID with the name Marchenko instead of Demjanjuk. What the supreme court didn’t hear at the time was that Demjanjuk’s mother’s name was Marchenko and he even used that name on his US entry visa.
The Israeli supreme court didn’t find him not guilty, they overturned the ruling and made a statement “The matter is closed-but not complete, the complete truth is not the prerogative of the human judge.” They left open the legal door to keep going and not clear Demjanjuk.
These are very serious crimes for which the person responsible should die, but I would hope that the state (whichever state that happens to be) establishes concrete proof, beyond doubt, that this is the guy who did these things.
"Probably" isn't enough.
