INCREASING the distance between yourself and a potentially dangerous assailant is always a good idea - even if your ultimate aim is to render them insensible. That appears to be the thinking behind a Pentagon project, now in its final stages, to perfect a projectile capable of delivering an electric shock to incapacitate a person tens of metres away. It will be fired from a standard 40-millimetre grenade launcher.
The projectile, being developed by Taser International under a $2.5 million contract, is known as a Human Electro-Muscular Incapacitation or HEMI device. Taser will deliver the first prototypes for testing and evaluation early next year.
Wes Burgei, a project engineer at the US Department of Defense's Joint Non-Lethal Weapons Directorate (JNLWD), says the self-contained cartridges should be able to hit targets 60 metres away - more than three times the range of the existing XREP shotgun cartridge (New Scientist, 29 August, p 20).
However, the impact force of the projectile remains a worry. "There is a known risk of severe injury from impact projectiles, either from blunt force at short ranges or from hitting a sensitive part of the body," says security researcher Neil Davison, who has recently written a book on non-lethal weapons.
