From Computerworld:
The FBI has denied a request for the release of information regarding its use of Carrier IQ's software, saying that releasing the information could interfere with ongoing law enforcement operations.

The request under the Freedom of Information Act was filed Dec. 1 by Michael Morisy, co-founder of MuckRock, a website that helps people file FOIA requests with the government. Morisy asked the FBI for any manuals, documents or other written material it might have related to the FBI's use of data gathered by Carrier IQ.
