I smiled when I heard the news on Thursday. Justice had finally caught up with Ratko Mladić. To be honest, though, I didn’t always think that it would. Ten years ago, I was serving as the youngest prosecution attorney at the U.N. war crimes tribunal in The Hague. And, while I had great respect for the seasoned prosecutors and investigators hard at work, I couldn’t help but notice that it seemed incredibly challenging for the international community to capture its alleged war criminals.
