The Senate report's findings are not some surprisingly new or unforeseeable result. This was well established and repeatedly pointed out to the Bush administration.
Only in a deeply warped society would some weasel lawyers construct the kind of twisted logic that you are espousing. Your definition is so far outside the mainstream, it doesn't even qualify as a joke. So yes, it is irrelevant.
And while I am happy that you are not happy about this state of affairs, it doesn't make a yota of difference. Your rational is irrational and the method profoundly wrong.
As to being able to catch terrorists without torture, you didn't pay attention to what I earlier wrote. We got all the RAF bad guys and one of the worst terrorists before Bin Laden was caught the old fashioned way, with solid intelligence and diplomacy.
Terrorism was always a reality in most Western countries (but North America) and we dealt with it without misplacing our values.
If you never even heard of Hitchens it's a pretty save bet that you never heard about any of this foreign history, and live on a Faux News diet.
Maybe you should try to travel the world a bit.
