You can run, but you most certainly cannot hide... or at least you can't hide from the reported fifty or so police agencies that have been secretly using a radar device to detect movement behind walls.
What sounds straight out of science fiction is a reality, and Indystar.com explains how the scary device works:

The radars work like finely tuned motion detectors, using radio waves to zero in on movements as slight as human breathing from a distance of more than 50 feet. They can detect whether anyone is inside of a house, where they are and whether they are moving.
It's also reported that agencies such as the FBI have been using the devices without much public scrutiny for the past two years or so. However, growing concern regarding public surveillance coupled with a federal appeals case that found police had used the device to look into a man’s house without a search warrant, have thrown the device into scrutiny.
The device, also known as the Range-R is manufactured by threat detection technology company L-3 CyTerra. The company estimates to have sold about 200 of the devices to 50 agencies at $6,000 a pop.
This however isn’t even the most advanced technology of its kind. As Indystar.com reports:
Other radar devices have far more advanced capabilities, including three-dimensional displays of where people are located inside a building, according to marketing materials from their manufacturers. One is capable of being mounted on a drone. And the Justice Department has funded research to develop systems that can map the interiors of buildings and locate the people within them.
Looks like it's time for those tin foil hats, pants, and shirts!
