Yep, you must be a lawyer because you opened with an insult and then you give me some BS doublespeak. Facebook is bound by Ireland's laws and is all my contention is. Now prove me wrong, which you have not done.

Then again, a free thing disappears as well-

There's no insult, you're making that up. Telling you that you don't know what you're talking about, particularly in the way you are so certain is not in and of itself an insult.

Alright, under (Title) 18 US 2703, you can start there to see what compelling powers a US Government agency has.

Then you can go state by state to see what local state agencies can compel these companies with as as well. A Search Warrant is generally needed for most content- i.e., whether it is ECS content, (emails or other kinds of electronics communications), or if it's RCS content (such as stored files, pictures and images) a (d) Order might be sufficient. A subpoena would likely suffice for basic subscriber information. Due to the recent Warshak ruling in United States v. Warshak, et al., No. 08-3997 (6th Cir. Dec. 14, 2010), the government can no longer compel a company to provide email content in electronic storage over 180 days or more with a subpoena or court order, a Search Warrant is always needed.

I'm going to say it again- Facebook is a US based company. As such, its records are going to be subject to US jurisdiction, it makes no difference at all if the accounts belong to non-US residents, the accounts are the business records of a US company. Now, overseas jurisdiction will also have their own mechanisms to obtain information from Facebook as well.
