Why do leading US politicians advocate cold blooded murder by government troops?
Because he is effectively a terrorist. In all of the reports that I have read I have yet to hear revelations about the US killing babies and doing horrible things. If those were the kinds of things being reported this case would be very different. Instead diplomatic cables claiming the the Prince of England is an ass have been released. That only serves to hurt the US's relationship with other nations, and generally hurt its international standing. If these same documents had been released by Osama Bin Laden we would say it is yet another terrorist attack. Instead they have been released by a person who in the past has done good things in the name of public disclosure of information. I fail to see the value in this latest release and as a result I am right in line with whichever US politicians are advocating cold blooded murder.
