ACLU Says NSA Surveillance Unconstitutional, Has "Chilling Effect"

Latest court motion in ongoing lawsuit

The National Security Agency's mass tracking and collection of Americans' phone call data violates the constitution, has a chilling effect on first amendment rights and should be halted, accord to a court motion filed by the American Civil Liberties Union on Monday.

In a detailed, legal critique of the NSA programme, the ACLU warned that such long-term surveillance "permits the government to assemble a richly detailed profile of every person living in the United States and to draw a comprehensive map of their associations with one another."
