The "Company" destroyed videotapes of "enhanced interrogations"(read torture sessions) in what seems like a de facto admission of guilt. In conclusion my opinion is that(even without hindsight), what then VP Dick"Lon" Cheney coyly termed "working on the dark side" after 9/11 turned into the blindest of blind alleys for the CIA( the FBI wisely rejected such tactics; one enterprising agent reportedly got an AQ suspect to talk not by "waterboarding" him but upon discovering that he was borderline diabetic , by feeding him sugar free cookies).
As for specious arguments that only "bad guys" deserve such treatment, this glibly ignores the fact that torture has a tendency to be self perpetuating as well as to grow- today it could be suspected jihadists- tomorrow it could be paedophiles, mafiosi, gang members, serial killers, violent white supremacists or YOU!!
Ditto for arguments that those involved in such barbarous activities were "good family men and patriots"( many Axis war criminals and mafia bosses could be so referred to)!
