I am curious to know how Snowden is financing his travel, lodgings and meals at this point since, presumably, his access to US financial accounts has been cut off. Does a warrant for arrest enable US authorities to place a hold on his accounts? Without a residency visa of some kind, it is difficult to open foreign financial accounts abroad. Perhaps he has a bag full of cash although that may create some issues of its own with various immigration authorities.
