The British government has refused a diplomatic request from the United States for "shoot-to-kill" immunity for armed American special agents and snipers who will be travelling to Britain as part of President Bush's entourage this week, which means that if they accidentally kill a protester, they'll have to stand trial for it. The Brits are also balking at the Bush team's demand that they shut down parts of London's Tube (subway) system and that they create a "sterile zone" around the President to keep the public at bay. The U.S. has also been denied permission to use its "mini-gun," a piece of military hardware that is fired from a tank and can kill dozens of people. (We're not making this up, honest!)
