Sometimes it seems that the only way to make sense of the Bush administration is to imagine that it’s a vast experiment concocted by mad political scientists who want to see what happens if a nation systematically ignores everything we’ve learned over the past few centuries about how to make a modern government work.

Thus, the administration has abandoned the principle of a professional, nonpolitical civil service, stuffing agencies from FEMA to the Justice Department with unqualified cronies. Tax farming — giving individuals the right to collect taxes, in return for a share of the take — went out with the French Revolution; now the tax farmers are back.

And so are mercenaries, whom Machiavelli described as “useless and dangerous” more than four centuries ago.
...

For example, Mr. Singer reminds us that in 2005 “armed contractors from the Zapata firm were detained by U.S. forces, who claimed they saw the private soldiers indiscriminately firing not only at Iraqi civilians, but also U.S. Marines.” The contractors were not charged. In 2006, employees of Aegis, another security firm, posted a “trophy video” on the Internet that showed them shooting civilians, and employees of Triple Canopy, yet another contractor, were fired after alleging that a supervisor engaged in “joy-ride shooting” of Iraqi civilians.

Yet even among the contractors, Blackwater has the worst reputation. On Christmas Eve 2006, a drunken Blackwater employee reportedly shot and killed a guard of the Iraqi vice president. (The employee was flown out of the country, and has not been charged.) In May 2007, Blackwater employees reportedly shot an employee of Iraq’s Interior Ministry, leading to an armed standoff between the firm and Iraqi police.

Iraqis aren’t the only victims of this behavior. Of the nearly 4,000 American service members who have died in Iraq, scores if not hundreds would surely still be alive if it weren’t for the hatred such incidents engender.

Which raises the question, why are Blackwater and other mercenary outfits still playing such a big role in Iraq?
