During a debate on the National Security Agency’s bulk surveillance programs, Michael Hayden, a former CIA and NSA director, admitted that metadata is used as the basis for killing people.
The comments were made during a debate at Johns Hopkins University. David Cole , a Georgetown University Law Center professor, detailed the kind of information the government can obtain simply by collecting metadata. Who you call, when you call them, how long the call lasts, and how often calls between the two parties are made.

NSA supporters often make the claim that such metadata collection is permissible considering the content of the call is not collected. Professor Cole argued that is not the case, since the former general counsel of the NSA, Stewart Baker, has already stated metadata alone is more than enough to reveal vast amounts of an individual’s personal information.
