There's some doubt as to the legitimacy of those flyers. Pushilin's organization denies they have any legitimacy; they were handed out by masked men in front of a synagogue. I could put on a balaclava and go stand in front of the local Catholic church and hand out mimeographed flyers with the seal of the Democratic party telling the local Catholics to register and, while it would give Limbaugh a good talking point, wouldn't prove that Obama was going to put Catholics in camps.
I'm getting very skeptical of both sides here; Putin is a warmongering territory-grabbing dictator, but on the other hand, Western governments are grabbing at straws to make him look just like Hitler (only not the really bad kind of Hitler you need to go to war to stop.)
