I've never seen Sen. Claire McCaskill quite so fired up about, well, anything:

A committee investigation of the company revealed that contracting personnel acquired hundreds of weapons, including more than 500 AK-47s, from a facility in Kabul that stores arms for use by the Afghan police. The contractors were not authorized to be armed.

Democratic Senator Claire McCaskill says if members of the U.S. military were involved in such actions they would face immediate and serious consequences.

"If one of the Army had gone out there with an AK-47 they were not supposed to have on top of a moving vehicle and shot a guy in the head and paralyzed him something would have happened in that chain of command," said Claire McCaskill.

"And if they had kept somebody on the force that had been using cocaine, that had been drunk, that had been charged with larceny that had done all these things these guys had done, they went out and killed Afghan people in the spring of 2009, something would have happened to them if they were in the military."

Senator McCaskill says most Afghans do not distinguish between private American contractors and members of the U.S. military.

She says reckless behavior by contractors is jeopardizing the U.S. mission in Afghanistan.

"And what is killing me about this problem with Blackwater is we have two sets of rules and one image," she said. "And as long as we have two sets of rules and one image we are in trouble on this mission."
