Very cool that FB provides info to law enforcement authorities on due process. It would be even cooler if I really trusted FB, but that’s another matter.
So, you want someone’s FB info? You will need one of:
- A valid subpoena issued in connection with an official criminal investigation
- A court order
- A search warrant showing probable cause, or
- A national security letter.
