And what's still out there, in the way of Nazi war criminals. Someone age 20 in 1945, would be pushing 90 now. All that's likely left are low level people, at best.
Also, in the interests of political expediency, healing, and what not it was decided that they'd go after the high and mid-level types and not the 'peons', though I understand that many of them ended up convicted and executed as well.
I remember on guy who was on trial as a suspected concentration camp for something like the 3rd time. Where I decided that they should just let the guy go:
1. He was suffering from dementia. Unable to properly defend himself.
2. WHO he was being accused of being had changed for the 3rd time, with them saying he was at a DIFFERENT camp than the first, this time, as well as being a completely different person working a different job. I got the distinct impression they were targeting specifically him, with any concentration camp worker not otherwise confirmed.
3. Most of the potential witnesses were either dead or suffering from a level of dementia as well.
4. Do you really expect to recognize somebody when you haven't seen them for 60+ years?
5. Besides political points, what are you really getting? The privilege of providing medical care to a man who doesn't even know where he is anymore, that would have been taken care of by his family back in the states without this?
