CIA Trained Scorpions Do "the dirty work" in Iraq

That I am no longer surprised by stories like this, that I wondered if it was worth posting tells me just how far we've slid down the slippery slope where the ends justify the means.  We spent millions of dollars to train the Scorpions, an Iraqi paramilitary group, to aid in the initial war effort.  But when that mission largely failed, the Scorpions turned into a loosely supervised group of thugs available to do “the dirty work” during interrogations:

Before the War, CIA Reportedly Trained a Team of Iraqis to Aid U.S., By Dana Priest and Josh White, Washington Post:  Before the war in Iraq began, the CIA recruited and trained an Iraqi paramilitary group, code-named the Scorpions, to foment rebellion, conduct sabotage, and help CIA paramilitaries who entered Baghdad and other cities target buildings and individuals … The CIA spent millions of dollars on the Scorpions, whose existence has not been previously disclosed ... But most of the unit's prewar missions -- spray-painting graffiti on walls; cutting electricity; "sowing confusion," as one said -- were delayed or canceled because of poor training or planning ... The speed of the invasion negated the need for most of their missions, others said.  After Baghdad fell, the CIA used the Scorpions to try to infiltrate the insurgency, to help out in interrogations, and, from time to time, to do "the dirty work," as one intelligence official put it.  In one case, members of the unit, wearing masks and carrying clubs and pipes, beat up an Iraqi general in the presence of CIA and military personnel. … Rep. Peter Hoekstra (R-Mich.), chairman of the House intelligence committee, asked if he was satisfied with the information he received on the unit, said, "Yes -- if it existed." But he added: "We're not spending a lot of time going back and dissecting tactical programs." … Authorized by a presidential finding signed by President Bush in February or March 2002, the Scorpions were part of a policy of "regime change" in Iraq. ...  After the initial combat phase of the war, the CIA used the paramilitary units as translators and to fetch supplies and retrieve informants in an increasingly dangerous Iraq … CIA control over the unit became weaker as chaos grew in Iraq. "Even though they were set up by us, they weren't well supervised," said an intelligence official.  "At some point, and it's not really clear how this happened, they started being used in interrogations . . . because they spoke the local dialect" and were caught roughing up detainees, Curtis E. Ryan, an Army investigator, told a military court in Colorado ... 

This statement says it all:

"We're not spending a lot of time going back and dissecting tactical programs." 

Why not?
