I don’t necessarily believe this. Might be a way to try to get some Serbs to turn on Mladic and then rat on his whereabouts. Something smells fishy here. Why would Mladic do this, give info on Karadzic. What would it gain him? He hasn’t been caught yet to want to try to bargain by using Karadzic as a chip. I don’t know. This just doesn’t strike me right. I think it’s a lie.
Agreed, it doesn't make sense. Because helping them catch Karadzic, would mean that they could focus all their attention on catching Mladic. There's no advantage in it for Mladic to do this.
I think that they are just using this story as "bait" for Mladic to surface, or use someone to deny it so that they can track them. And also to smear Mladic's reputation. Also maybe to throw people off the scent of who really located Karadzic.
