LOL funny part about those scams is if the FBI were looking for you, ummm MIB (Men in Black) would be visiting you or is it blue suits !LOL Same with the CIA and other agencies..
Sad part is many people fall for these scams via the internet and taken to the cleaners, then the FBI, CIA etc.. all get involved as they all have an internet crimes unit(so I have been told). But the people who are doing this-move from location to location and have a way of disguising their IP address.
