I've Seen the Future, and It Has a Kill Switch

Bruce Schneier:

It used to be that just the entertainment industries wanted to control your computers -- and televisions and iPods and everything else -- to ensure that you didn't violate any copyright rules. But now everyone else wants to get their hooks into your gear.

OnStar will soon include the ability for the police to shut off your engine remotely. Buses are getting the same capability, in case terrorists want to re-enact the movie Speed. The Pentagon wants a kill switch installed on airplanes, and is worried about potential enemies installing kill switches on their own equipment.

Microsoft is doing some of the most creative thinking along these lines, with something it's calling "Digital Manners Policies." According to its patent application, DMP-enabled devices would accept broadcast "orders" limiting capabilities. Cellphones could be remotely set to vibrate mode in restaurants and concert halls, and be turned off on airplanes and in hospitals. Cameras could be prohibited from taking pictures in locker rooms and museums, and recording equipment could be disabled in theaters. Professors finally could prevent students from texting one another during class.

The possibilities are endless, and very dangerous. Making this work involves building a nearly flawless hierarchical system of authority. That's a difficult security problem even in its simplest form. Distributing that system among a variety of different devices -- computers, phones, PDAs, cameras, recorders -- with different firmware and manufacturers, is even more difficult. Not to mention delegating different levels of authority to various agencies, enterprises, industries and individuals, and then enforcing the necessary safeguards.

NSA's Domestic Spying Grows As Agency Sweeps Up Data

Siobhan Gorman:

Five years ago, Congress killed an experimental Pentagon antiterrorism program meant to vacuum up electronic data about people in the U.S. to search for suspicious patterns. Opponents called it too broad an intrusion on Americans' privacy, even after the Sept. 11 terrorist attacks.

But the data-sifting effort didn't disappear. The National Security Agency, once confined to foreign surveillance, has been building essentially the same system.

The central role the NSA has come to occupy in domestic intelligence gathering has never been publicly disclosed. But an inquiry reveals that its efforts have evolved to reach more broadly into data about people's communications, travel and finances in the U.S. than the domestic surveillance programs brought to light since the 2001 terrorist attacks.

Prosecutor Over-Reaching

Dee Hall covers an issue vital to our democracy - over zealous prosecutors:

A Wisconsin State Journal investigation, however, found instances in which court records and transcripts back up his critics' claims that he has crossed ethical lines. Stretching back to the early 1990s, Humphrey has been the subject of criticism accusing him of ethical lapses, poor judgment and unreasonably aggressive tactics. Critics have included defendants, defense attorneys, judges and three of the four district attorneys who've supervised him.

The State Journal examined more than 2,000 pages of documents, including records from Humphrey's office files obtained under the open-records law. The newspaper also interviewed more than two dozen attorneys, judges, defendants, legal experts and law-enforcement officials.

The newspaper's investigation found that the veteran prosecutor:

— Wrongfully kept a young man in the Dane County Jail for a month, even after he was repeatedly notified of the error.

— Made false or misleading statements in affidavits, in correspondence and in court hearings to advance his case or to cover up mistakes.

— Charged two witnesses and had a third arrested for failing to show up for trials that had been cancelled — a tactic his boss had warned him was "an abuse of your authority."

— Aggressively pursued seven felony charges against a bankrupt father who was $2,846 behind in child support — a prosecution the judge said should "make one wonder about the integrity of (the) justice system."

— Twice pursued vehicular-homicide charges using speed estimates his own experts told him were inflated.

One of those cases was Humphrey's failed prosecution of Adam Raisbeck, a 17-year-old from Marshall. Humphrey's actions in the case prompted a blunt reprimand from his boss, and the misconduct findings that are headed to the Supreme Court.

US District Judge Lewis Kaplan recently expressed concern over "prosecutor's expansive power".
