Donald Rumsfeld was Reagan's messenger boy - completely unofficial,

So how on earth, if he was unofficial did he get the power to speak for the US government? He was chosen by Reagan as a messenger boy - putting the word "unofficial" especially when it is untrue, makes no difference to that. So he fully revealed his role four years later? So what?

As far as Blackwater and its role is concerned - they are not being sued for their role in Iraq, the people are trying to sue them for negligence in fulfilling that role.

They are claiming immunity from having this negligence being tested in court. Claiming immunity for killing Americans by negligence. I reckon most people can see that.

What a strange set of values supporting them has brought you to.
