So, the continuing education of Radovan Karadžić included a spell at a private school for "bioenergetics" in Belgrade, where he received the title of "general for poisons, gold and minefield injuries" (I am not making this up). It was Mina Minić, the director of the school, who gave him the nickname "David" because, she says, he was very curious and wanted "to see" (da vidi) everything.
I am just posting stuff I read. I am not making it up. What makes you think I could make this up?
Update: Oops, sorry, gender confusion. Apparently Mina Minić is a dude. And here is (perhaps) a photo.
