Low Level HERFs For Police

Here is an article on a low-level device which is to be made available to even regular police. My point is, that there is technology which emits waves which are destructed, and these are readily available in law enforcement, some even at the lower levels of the food chain. HERFs, stands for high energy radio frequency weapons (particularly microwaves). I've included an article by The Guardian below:

Police test hi-tech zapper that could end car chasesIan Sample, science correspondent guardian.co.uk, Monday July 12 2004 02.43 BST The Guardian, Monday July 12 2004 Article historyA hi-tech device that can bring speeding cars to a halt at the flick of a switch is set to become the latest weapon in the fight against crime.

Police forces in Britain and the US have ordered tests of the new system that delivers a blast of radio waves powerful enough to knock out vital engine electronics, making the targeted vehicle stall and slowly come to a stop.

David Giri, who left his position as a physics professor at the University of California in Berkeley to set up a company called ProTech, is developing a radio wave vehicle-stopping system for the US marine corps and the Los Angeles police department.

Tomorrow, at the Euroem 2004 science conference in Germany, Dr Giri will describe recent trials of the device. The tests proved that the system could stop vehicles from up to 50 metres away.

The bulk of the device is designed to fit in a car boot and consists of a battery and a bank of capacitors that can store an electrical charge. Flicking a switch on the dashboard sends a burst of electricity into an antenna mounted on the roof of the car. The antenna then produces a narrow beam of intense radio waves that is directed at the vehicle ahead.

When the radio waves hit the targeted car, they induce surges of electricity in its electronics, upsetting the fuel injection and engine firing signals. "It works on most cars built in the past 10 years, because their engines are controlled by computer chips," said Dr Giri. "If we can disrupt the computer, we can stop the car." A prototype is due to be ready by next summer.

The Association of Chief Police Officers confirmed that researchers at the Home Office's police scientific development branch are testing a radio wave vehicle-stopping system. "There's a potential to use this type of device to stop criminals on the road. High speed pursuits are very dangerous, especially in built-up areas," said an association spokesman.
