whether the court had given blanket legal approval for the entire NSA program. The ACLU said in a statement that "without more information about what the secret FISC has authorized, there is no way to determine whether the NSA's current activities are lawful". Law professor Chip Pitts argued that substantial legal questions remain regarding the core NSA program as well as the related data mining program (and the use of National Security Letters), despite the government's apparently bringing the NSA program within the purview of FISA.

The term "unreasonable" connotes the sense that a constitutional search
