The American Army, going back to the Administration of George Washington has NEVER refused an order to fire on civilians. NEVER. Not in the Whiskey Rebellion, or the Civil War, or urban/campus riots, or - and perhaps the most glaring example - on their own (once) fellow soldiers. (See: Bonus Army march on Washington, "Occupy" is not a new concept.) The solider that carried out the orders that included shooting veterans of the First World War? Douglas MacArthur. The carvery charge was led by George Patton.
