Weapons that can incapacitate crowds of people by sweeping a lightning-like beam of electricity across them are being readied for sale to military and police forces in the US and Europe.
At present, commercial stun guns target one person at a time, and work only at close quarters. The new breed of non-lethal weapons can be used on many people at once and operate over far greater distances.
But human rights groups are appalled by the fact that no independent safety tests have been carried out, and by their potential for indiscriminate use.
The weapons are designed to address the perceived shortcomings of the Taser, the electric-shock gun already used by 4000 police departments in the US and undergoing trials with some police forces in the UK.
It hits the victim with two darts that trail current-carrying wires, which limit its range to a maximum of seven metres (see graphic). As a single shot, short-range weapon, the Taser is of little use in crowd control. And Tasers have no effect on vehicles.
Ionised gas
These limitations are beginning to be overcome. Engineers working for the US Department of Defense's research division, DARPA, and defence companies in Europe have been working out how to create an electrically conductive path between a gun and a target without using wires.
A weapon under development by Rheinmetall, based in Dorf, Germany, creates a conducting channel by using a small explosive charge to squirt a stream of tiny conductive fibres through the air at the victim (New Scientist print edition, 24 May 2003).
Meanwhile, Xtreme Alternative Defense Systems (XADS), based in Anderson, Indiana, will be one of the first companies to market another type of wireless weapon. Instead of using fibres, the $9000 Close Quarters Shock Rifle projects an ionised gas, or plasma, towards the target, producing a conducting channel. It will also interfere with electronic ignition systems and stop vehicles.
"We will be able to fire a stream of electricity like water out of a hose at one or many targets in a single sweep," claims XADS president Peter Bitar.
