Declan McCullagh has the story on the latest in back-door spyware demanded by US police agencies:

CNET has reviewed a survey scheduled to be released at a federal task force meeting on Thursday, which says that law enforcement agencies are virtually unanimous in calling for such an interface to be created. Eighty-nine percent of police surveyed, it says, want to be able to "exchange legal process requests and responses to legal process" through an encrypted, police-only "nationwide computer network."

(See one excerpt and another.)

The survey, according to two people with knowledge of the situation, is part of a broader push from law enforcement agencies to alter the ground rules of online investigations. Other components include renewed calls for laws requiring Internet companies to store data about their users for up to five years and increased pressure on companies to respond to police inquiries in hours instead of days.

But the most controversial element is probably the private Web interface, which raises novel security and privacy concerns, especially in the wake of a recent inspector general's report (PDF) from the Justice Department. The 289-page report detailed how the FBI obtained Americans' telephone records by citing nonexistent emergencies and simply asking for the data or writing phone numbers on a sticky note rather than following procedures required by law.

Some companies already have police-only Web interfaces. Sprint Nextel operates what it calls the L-Site, also known as the "legal compliance secure Web portal." The company even has offered a course that "will teach you how to create and track legal demands through L-site. Learn to navigate and securely download requested records." Cox Communications makes its price list for complying with police requests public; a 30-day wiretap is $3,500.

As we just learned again with Chinese hacking into Gmail accounts, this kind of software is wide open to abuse, and not just by the people it was built for.
