“Do we even know that he did what the NKs accused him of? How likely is it that he was 100% innocent and only read their prepared confession because he thought it might save his life?”
I seem to recall that there was a security video of him taking the poster.
However, his guilt or innocent under our standards of innocence until proven guilty is irrelevant in NK.
Yeah, that definitive picture of a blurry person placing something from the wall on the floor. Best video evidence ever to prove someone did something.
I defy anyone to identify Warmbier, let alone any person, in that video. Not that is makes a difference. What happened to him in inexcusable.
