you really seemed that dumb.And america doesnt govern the world. Also the FBI might be more powerful but i'd be much more scared of the Mossad. FBI has all the laws and shit and mossad doesn't really abide by that
America practically do govern the world. Everything that they do effects every other country. For example, I'll use SOPA. Internet censorship, it was an American bill, only destined for Americans. The amount of internet content and servers that would've gotten restricted in America would certainly of effected the rest of the world. Hell, they shut down megaupload which has already effected me and many other people that don't live in America, and the bill wasn't even passed!
FBI might have laws, but do they need to follow them? No. You really think they follow them? There are rules set in place about killing people, does that stop them from shooting terroists and trouble makers? No.
Just because they have rules doesn't mean they follow them, and do you really think that you see or hear about half the stuff that the FBI do? No.
