Where was the legal base when they seized the servers? First the DoJ starts off with some rant about Vinnik and Mt Gox. Mt Gox was not in the US, it was in Japan and Karpeles is not a US citizen he is French. So they seized the BTC-e servers with a search warrant, most likely they were sniffing for information to actually charge someone with something because they didn't have any. Think about that!
The U.S. agents seized funds from btc-e exchange. So if btc-e owners want to challenge the DoJ's decision in court, they need to reveal their identity first. How does that sound to you?
