Thousands of people die each year as a result of crashes during police car chases. The solution appears to lie in electro-magnetic pulse technology. During World War 2 and its aftermath, one of the things defence scientists quickly discovered is that nuclear explosions created massive electromagnetic pulses capable of stopping anything running on electricity in its tracks. A pulse could overload car ignitions or even aircraft in flight.
The Norwegians have been working on a scaled-down version of EMP technology to create a focused beam weapon capable of bringing cars to a stop, as this clip from NATO TV illustrates:
On the Internet, you can find instructions for converting a disposable camera into a stun gun. That's what happens, when technology goes viral.
What happens when the technology of EMP devices goes viral? What happens, for instance, when bank robbers can disable pursuing police vehicles?
Who needs a Stinger missile, when one can use an EMP device to down an aircraft coming in for a landing or a low-flying helicopter?
Unlike the explosion caused by a missile, an EMP device would leave no evidence of its use. It would simulate an equipment failure.
