You don't want to know, nor should you. Common knowledge is exactly that, and negates any element of surprise if they know just exactly what we're going to do. I could just spit over Obama's latest security breach.
I still consider interrogation techniques as a viable part of the intelligence organ, as distasteful as that may sound to some.
We can all quibble about the morality of interrogation and just exactly how the information should be extracted, but do we really want to discount the value of the timely intel collected from bad actors when the lives of our own sons and daughters are on the line?
It goes back to that saying, "We sleep soundly in our beds because rough men stand ready in the night to visit violence on those who would do us harm."
Violence can be all sorts of things, all sorts of
icky things that make people squeamish or even claim the moral high ground. Some even break down that violence into good and bad violence, to better assuage their conscience. To me, dropping 70K pounds of ordnance on Iraqis hunkered down in their trenches was no better or worse than waterboarding our buddy Khalid Sheikh Mohammed. I'm not so certain Mike Rowe would undertake performing the latter for a Dirty Jobs episode, but it is indeed a dirty job.
If it makes one feel any better, violence is also visited upon those who are selected to perform certain military functions, as a prerequisite to their training. It's not unlike cops getting tasered before they get their tasers issued. I won't go into specifics, but suffice it to say I was ordered to take a week or two's worth of leave after my "graduate" level survival courses to decompress. I was pretty much in shock afterwards for a while, because who would've thought that Uncle Sam could beat up one of their own both mentally and physically in the name of training? Sure, I'd seen the Navy SEALS videos, but they're SEALS, right?
Those same graduate survival courses got myself and several of my fellow USAF/Navy SRO aircrew members
volunteered (a military euphemism, if ever there was) at the end of my career to go play in the shithole that was Baghdad, because folks so trained could detect the evasion techniques used by detainees under interrogation, and help steer the questions accordingly.
It doesn't mean you have to be the resident APS warmonger, or even remotely like the concept, but you do what you have to do. LadySmith would make it really easy for me to get info out of her, but I was more than prepared to use the tools and training at my disposal to get answers. Been there, done that, got the tour credit and the fruit salad for my shadow box. Now all I can do is play mind games with my friends and family to either get a rise out of them or elicit answers when they try to be evasive. I've also been known to mess with the mental health folks at the VA during sessions. You'd think they'd learn to look up a vet's DD-214 before jumping in with both feet.
