He didn't mention Demanjuk, but every court that's looked at him says he was a camp guard. However he's being deported, since he entered illegally, not prosecuted. In general prosecution is done by the nation the crime was committed in. To my knowledge, run of the mill camp guards like Demanjuk aren't prosecuted very often.
Yes, I believe he was prosecuted, there was a trial, and Israeli judges found him innocent (I can't remember all the details - it was well over 18 years ago).
In fact, he was in the Israeli courtroom doing the sign of the cross (though he kept doing it backwards).
It happened in Cleveland, where I live.
He's a retired Ford worker, and it was/is big news.
The only thing they could prove was the immigration papers, and he's been biding his time on appeals with it.
