I say these people have got it completely backwards.
Now, to be fair, if you are a criminal, and you are investigated, your morale is going to suffer, but I'm not terribly concerned about that lot, are you? And, regrettably, since investigations have certainly gone wrong in the past, there will probably people who are innocent, but who have powerful bosses, or scumbag coworkers that will finger them to shift the blame. Well, these people who were close to all the action, their morale will suffer, too, and, as I said, this is regrettable. So, yes, the morale of the criminals and the people near them will suffer.
But I'd like you to put yourselves in the suit of a good CIA interrogator, a decent person, a decent human being. I'd like you to imagine that you never threatened to have someone's mother raped, that you never attached electrodes to a detainee's gonads, and that you didn't force them to sit in their own shit for 72 hours, or even one day. If you can't do this, if you can't imagine being a human being, then you'd might as well stop reading this, since the rest of this won't make any sense to you at all.
Now, from what I've heard, and this is based on the most recent information, there is no evidence whatsoever that serial fabulator Richard Cheney was correct when he said torture led to a stopped terrorist attack. None, zippo, nada.
So, you were the good interrogator, the human being, and you got your intelligence according to the rules, and some other interrogator broke the rules, and enjoyed beating people when no one was looking, and torturing people just because they were the enemy, not because there was any good intelligence to be had, and they are getting off scot free.
Well, I ask you, what's that going to do to your morale?
Hey, the guy who just beat you in the 50 meter dash is doping, but we are letting him off the hook, because we don't want to look backwards. Hey, the cop who just arrested you planted evidence, but we wouldn't want to investigate because it might demoralize the police. Hey, that politician just took Florida knowing full well the intent of 3,000 voters in Palm Beach County was to vote for Gore. Look forward, not backwards, my son.
In fact, it doesn't take a supra-genius to see that almost all criminal investigations are an exercise in looking backwards, mostly because we rarely ever prosecute people for murder unless someone has actually, and in the past, been wrongfully deceased.
But to hear Dick Cheney, a man wanted by some in the NSA for his crimes, you'd think investigating crimes is un-American.
It's easy to write off Cheney as "evil" or "batshit loony" but there might be a more reasonable explanation.
