    "Bad boys, bad boys, whatcha gonna do? Whatcha gonna do when they come for you?"...with radars that can "see" through walls. Because according to USA Today, at least 50 law enforcement agencies in the US, including the FBI and the US Marshals, have been stocking up on handheld radars for the past two years. The product they use is called Range-R (pictured above) manufactured by L-3 Communications, which is powerful enough to detect movement and even breathing within 50 feet, even behind one-foot thick walls of concrete. It also sees through wood, glass, dirt and most other materials used for walls -- except metal, that is. Plus, since the device has a 160-degree field of view, it only takes a few seconds to scan a house or any other location.
