The Committee finds that the domestic activities of the intelligence community at times violated specific statutory prohibitions and infringed the constitutional rights of American citizens. The legal questions involved in intelligence programs were often not considered. On other occasions, they were intentionally disregarded in the belief that because the programs served the "national security" the law did not apply. While intelligence officers on occasion failed to disclose to their superiors programs which were illegal or of questionable legality, the Committee finds that the most serious breaches of duty were those of senior officials, who were responsible for controlling intelligence activities and generally failed to assure compliance with the law.  Many of the techniques used would be intolerable in a democratic society even if all of the targets had been involved in violent activity, but COINTELPRO went far beyond that ... the Bureau conducted a sophisticated vigilante operation aimed squarely at preventing the exercise of First Amendment rights of speech and association, on the theory that preventing the growth of dangerous groups and the propagation of dangerous ideas would protect the national security and deter violence.
