Ah, I think we get to the crux of the matter, you seem not to perceive any innocents being harmed. You perhaps see the US as a single evil entity, and not a collection of disagreeing people living on a chunk of land.
Not if we care about truth vs falsehood, objective fact vs made up things, and an understandable world we can all fairly discuss. Even an axe murderer should be allowed to testify in his own defence. What if he is merely accused of axe murder, and the evidence has been fabricated and planted by corrupt police?
