Oh dear. CNN, in an effort to spice up its report on right-wingers protesting in Belgrade against the arrest of Radovan Karadzic, cut in footage of earlier riots. In Budapest. It is so blatant, with Hungarian flags and the Budapest metro (Belgrade has no metro) on full display. CNN yanked the video from their website, but it has cropped up on youtube (watch below).
It does make you wonder how often CNN, and some of its supposedly lower-rent peers, do this kind of thing and get away with it.
