Steven Aftergood at Secrecy News has links and the lowdown on two new Congressional Research Service reports that are worth a read. 

1. A new report from the Congressional Research Service explores ongoing legal debates over the tracking of private cell phones and vehicles by law enforcement agencies.

The 22 page CRS report provides a survey of relevant Fourth Amendment law, federal electronic surveillance statutes and case law, pending GPS-vehicle tracking cases, and electronic surveillance legislation that is before Congress.

2. “Compared with the White House, the executive branch, and the Supreme Court, the U.S. Congress is the most transparent national governmental institution,” the CRS report said.  “Yet the congressional process is replete with activities and actions that are private and not observable by the public.”
