From this interview from Julian Assange:
He believes the social network is joined by Google, Yahoo and other major US organisations that have “built in interfaces for US Intelligence”:
It’s not a matter of serving a subpoena, they have an interface they have developed for US Intelligence to use. Now, is the case that Facebook is run by US Intelligence? No, it’s not like that. It’s simply that US Intelligence is able to bring to bear legal and political pressure to them.
It’s costly for them to hand out individual records, one by one, so they have automated the process
Is the claim that US Intelligence has built-in interfaces in major social networking sites that allow them to browse personal information at will verified, or is it just guess-work by Assange?
