Facebook‘s legal department is ready for a fight. Almost every day, law enforcement officials and civil litigators request information from a user’s Facebook account, deputy general counsel Mark Howitson said.

But the social networking site is loath to provide it, Howitson reassured a standing-room-only audience during Tuesday’s keynote speech at LegalTech New York. That’s because the federal Electronics Communications Privacy Act prohibits the company from handing over any information about its 350 million users without a subpoena, unless someone gives his or her consent.
