The US Electronic Privacy Information Center (EPIC) has issued a lawsuit against the FBI, as it continues its push for more information about surveillance practices.
"EPIC has filed a Freedom of Information Act lawsuit to obtain details about the Federal Bureau of Investigation's surveillance programs. The agency is required to conduct privacy impact assessments when it collects and uses personal data," it said.
"However, the Bureau has failed to publicly release privacy impact assessments (PIA) for many of its programs, including facial recognition, drones and licence-plate readers."
The FBI is required to release the information by the guidelines of the US Justice Department and through the rules of the E-Government Act. EPIC said that such information is expected to be released if it is "practicable".
EPIC has already made a move on the documents, and in June is raised its first Freedom of Information request on the FBI and its PIA reports. In its history of the issues it said that the FBI has admitted to using a range of technologies, including drones, and has admitted to their use in watching US citizens.
"Privacy assessments are a critical part of assessing the level of intrusiveness new technologies could have on ordinary citizens. The assessments are required by law and provide transparency to the public," it said.
"EPIC's Freedom of Information Act litigation is designed to reveal where this transparency is lacking and highlight those privacy-evasive programs that still lack proper assessments of their impact on privacy."
We have contacted the FBI for a response.
