Big Brother Making Strides in Technology

Top researchers are developing new surveillance technology, the BBC reports - including "gait DNA" to identify a person by their walk and advanced spy drones that can fly overhead for years. The Pentagon plans to continue its tech supremacy, which includes inventing the Internet in the 1970s and satellite navigation in the 1990s. What's next in spy tech? "I'd prefer not to say," says a Pentagon researcher.

About 75% of people in the US and UK say they want more surveillance, and some US cities are considering Britain’s multi-million-camera monitoring system to keep track of citizens. Soon, a new radio device will be able to tell if someone’s waiting in the next room. One expert says that in 10 years, “We'll scan a person with one of these things and tell what they're actually thinking." (More domestic surveillance stories.)
