Well, I must confess, I almost had a Russian visa debacle in Ukraine. I thought I had done my homework, but the laws change so often, it was a mess, anyways, I was able to get a Russian visa in Kiev even though I am a US citizen with some help from the very kind locals, but that's a story for another day.
As far as Bradley Manning, well I don't know. No, I don't think he should be shot. I don't really know enough about the subject to make any real good calls on it, other than I've heard that the Wikileaks people themselves say that he had nothing to do with it, and how such a low ranking member of the army could have so much access to classified material is beyond me.
In short... I don't know! If he is guilty, then I suppose a sentence for treason could be carried out, on the other hand, I don't know the law pertaining to publishing documents that were classified. Its really an interesting case, and as far as I know, its one of the first of its kind.
