Is Blackwater security, Bush's version of Hitler's Gestapo?

After years of black eyes the government has taken for being caught doing dirt, they finally had sense enough to contract out the dirt they need done without being implicated themselves. That is what Blackwater is,essentially. People of all races need to wake up to what you see with your own eyes and stop letting the government tell you what you saw. We have one of,if not the best, militaries in the world. Why do we need Blackwater? What can they do that our military can't? They can kill and not have to answer to anyone. The government hands them their "ignments", they fulfill them and they don't answer to anyone. And most importantly,the image of our "pristine" government remains unblemished largely because they simply hired someone else to throw the rock.
