Can someone explain why the United States got involved with FIFA? It seems like they obviously had support from other nations to arrest these individuals but I wonder why the United States was the one to bring charges.
They will have had the support of local police. In fact, I pretty sure they would need it. If they don't have permission to be there then they could be arrested and probably would if they just went around arresting people. I don't think they can make arrests themselves but the local police can and then deport them to the states or wherever they're facing trial, but you know how much America likes sticking its nose in to other people's business.
