Intelligence Activities and the Rights of Americans: The Overbreadth of Domestic Intelligence Activity [open pdf - 81KB]
"The Committee finds that domestic intelligence activity has been overbroad in that (1) many Americans and domestic groups have been subjected to investigation who were not suspected of criminal activity and (2) the intelligence agencies have regularly collected information about personal and political activities irrelevant to any legitimate governmental interest. The central problem posed by domestic intelligence activity has been its departure from the standards of the law. This departure from law has meant not only the violation of constitutional prohibitions and explicit statutes, but also the adoption of criteria unrelated to the law as the basis for extensive investigations of Americans."
