Long-range Taser raises fears of shock and injury

"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.

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."
