One of the hard things about hunting down Osama was he was in a different country. When you are a wanted criminal or terrorist and you go to another country there’s a lot of legal stuff that goes on for trying to bring them back. One of those struggles is the country’s decision to actually hand over the criminal. They may have happened but in that concern I’m not quite sure of. There’s also the fact that he was probably hiding for those ten years but hey ended up finding Osama with a satellite. Hope this helps!
