According to European data protection law every individual has the right to get a copy of all personal data a company holds about him (right to access). This law is applicable to facebook too, since every European user has a contract with “Facebook Ireland Limited”, based in Dublin, Ireland.
Facebook has a well hidden page, where you can send them an access request.
Generally all nonusers have the same right to access data that Facebook might hold about them.
Note: So far, all regular letters mailed to Facebook Ireland Ltd. were ignored.
