Yeah, it's "Blackwater", my mistake. Shows how much regard I have for them that I can't get their silly name right (though we're not the first to make this semantic slip-up:

Chris, no personal offence taken whatsoever. It is an interesting problem. Against my better judgment I'll respond to your post because I think this is a very serious issue and opinions are still forming about it, and not necessarily along traditional right/left lines as I'll explain below. So I hope what I write may have some value and not be so highly political because ideology concerning this issue has not become entrenched yet.
I've read lots of arguments/excuses for why Blackwater and their kind are okay but none of them sit well with me or are particularly convincing. I think many people share my anxiety that if we allow paramilitary corporations to start popping up everywhere and replacing the traditional armed forces, they have the potential to grow out of our control.
-First, not everyone that works at Blackwater is former special forces or "elite". If they were it would be a pretty geriatric force. A lot are just police officers or private citizens. The only training they share in common is attending Blackwater's facility which may or may not be up to the high training standard of the REAL US military.
-Whether turning against one's own government is officially "legal" or not is irrelevant to a mercenary force. Mercenary companies have demonstrated time and again that they operate above the law of any country or for that matter, any ethical code. That's part of why they signed up to be mercs - they like operating outside the rules. In former Yogoslavia DynCorp employees were involved in the illegal trade of children against their will for "you know what". Blackwater employees have been charged with smugling weapons into Iraq for the "Kurdish Workers Party" to use, a terrorist force according to the US and UN. When your main loyalty is making money, who is to say that one day one of the mercenary corporations might not suddenly switch sides? Remember, Blackwater is apparently now close to a brigade-sized force and they are stacked with guys recruited from all over the world, including Russia and South America who may not have the same loyalty to the host country.
-It's not just that they'll turn against their own government. It's that they can freely commit war crimes without being held to the same standards of accountability and justice as normal military personal. Blackwater has almost lost its license a couple of times due to gunning down innocent people unprovoked. Several military commanders in Iraq have commented that they are like a bunch of reckless gun-toting cowboys, stirring up a hornets nest wherever they operate and ultimately doing more harm than good in terms of winning hearts and minds.
-I agree the privatization of war is going to continue into the future, now that Iraq has set the model. Private contractors will also increasingly be turned against the population of their home country, as happened during Hurricane Katrina when armed Blackwater troops were contracted (without any bidding) to enforce security in the disaster zone, and, presumably, shoot American citizens on site with little accountability for their actions. Anyone that worries about the state exercising unchecked power against it's citizens should be concerned by this development. A mercenary force is the antithesis of the citizen's militia, the idea enshrined in the US Constitution and the main reason for the right to bear arms in the US. Mercenaries are citizens motivated by profit to enforce the state's agenda, even if it might be fascist. A militia, on the contrary, are citizens motivated by love of country and patriotism who are prepared to fight for their rights and freedoms against the excesses of the state.
I could go on, but you get the idea. Mercenaries are in violation of the Geneva convention for a reason. And ultimately, I morally object to the idea of killing for profit. I shake my head at the fact that our Western values have slid to the point where we think mercs are perfectly acceptable. Traditionally mercs have been more of an Eastern idea. Hannibal employed them heavily but the Romans did not because they wanted loyal citizen soldiers who served for love of country not love of money.
