Systems within the scope of this paragraph may draw on and retain pertinent information from any source permitted by law, including information derived from past or ongoing investigative activities; other information collected or provided by governmental entities, such as foreign intelligence information and lookout list information; publicly available information, whether obtained directly or through services or resources (whether nonprofit or commercial) that compile or analyze such information; and information voluntarily provided by private entities. Any such system operated by the FBI shall be reviewed periodically for compliance with all applicable statutory provisions, Department regulations and policies, and Attorney General Guidelines.
2. Visiting Public Places and Events
For the purpose of detecting or preventing terrorist activities, the FBI is authorized to visit any place and attend any event that is open to the public, on the same terms and conditions as members of the public generally. No information obtained from such visits shall be retained unless it relates to potential criminal or terrorist activity.
