The FISA Immunity Act only prevents the states from conducting investigations. The Act does not expressly forbid any federal grand jury from conducing an investigation of alleged FISA violations, especially those alleged violations which fall outside the permissible activity covered by the immunity provisions.
LulzSec recently disclosed a list of Atlanta Infra Gard members The list points to people who have expertise in the computer, telecommunications, and information security fields. These people would, in theory, have some indirect informaiton related to communications or evidence required to successfully implement a plan to conduct surveillance per FISA.
The list also helps identify specific conversations related to computer maintenance and training, presumably part of the necessary TSP-like-support activities after 2001.
This is a space to share your inputs for "draft grand jury subpoenas" to Atlanta Infragard members and personnel re alleged FISA violations. The subpoenas are not an assertion of guilt, merely a request for information from the people publicly disclosed on the LulzSec-provided list of Atlanta Infragard personnel, agencies, and members.
The request for information can include a request for explanation of any disclosed conversation the Atlanta Infragard members have that may have bearing on investigating permissible reviews of alleged FISA violations.
If you have information related to evidence, conversations, activities, or any other information which may be of interest to a Federal Grand jury investigating FISA violations outside what the Immunity Act lawfully immunizes, feel free to share that information so that it may be included in the draft Grand Jury subpoenas for the Federal District Court.
