I'm saying that instead of acting vigilante style, how about writting a letter to the world court to try him if there is a valid case agaisnt him. If however the argument is that we can't do that because the USA is too poweful, then rather than waste time on what we can't change, let's do something productive and petition Canada to withdraw from NATO. And if that fails, then obviously we too are complicit in this making the US too powerful, in which case we are partly to blame too.
None of us disagree with your sentiment.
But it does not disparage from the point that we can have perfectly lawful protests against whatever policy or people we choose and none of these protests warrant barring an individual from entry to the country unless there is some jurisprudence for it.
And Cheney decided himself not to come in. Why? Because he's afraid of protesters getting through a wall of law enforcement?
Please.
