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.
Well... because the United States is acting like the world police. You need to understand certain facts. These are:
1. The Americans can arrest anyone (i.e any foreign citizen) anywhere.
2. No foreign nations can arrest American citizens.
3. Corruption is OK, as long as it favors the Americans.
4. No one should question the world police.
