Sometimes "wildly impractical hypotheticals" become real. That is my point.
That's not your point. Your point is that we should provide exceptions to the law for wildly impractical hypothetical situations where torture may or may not provide information that will save lives.
Again: how would you know that torturing someone would provide the information you seek in these hypotetical situations? And if you don't know that in advance, what happens to your jstification for torture?
This is an absolutely practical question which you keep evading.
