Further down in the comments, you indicated it was OK in the case of Nazi Germany since it wasn't "real" law enforcement and it "involves certitude". That seems to indicate to me that you don't actually believe it's "invariably wrong".
OK, easier scenario: A guy is insane, and is going to murder 20 people. Your only option is to ask his friend to kill him. Is is still "invariably" wrong?
Anyways, my original question to you (and on other threads, like where you appear to defend seizure actions) is where exactly are you getting your priors? In all your replies you just rephase things as if we're supposed to draw the right conclusion.
And I'm only asking because it's you, someone proven in security and rather insightful on many threads.
If it's just an innate, fundamental belief you hold, fine. I was just wondering if you had some special source or logic that lets you decide these things so absolutely.
