This was passed on by a reader in the comments last night (see below) but I was too tired to follow it up. Interesting little bit of speculation / conspiracy theory. Was the source of the information that led to the arrest of Karadžić none other than -- Ratko Mladić?
The way the story goes, Mladić is negotiating the terms of his own surrender, wants to avoid being tried, and passed on what he knew about his former co-conspirator to soemone, possibly the German intelligence agency BND.
It's all very interesting, though the article is short on detail and a bit rambling. According to my sources, Mladić is living under an assumed identity and working as an alternative pedicurist in Kuršumlija.
On the other hand, the more I look at the article, the more it looks like it was planted there, and not by a person skilled in feng shui.
