Maximum Pain is Aim of New US Weapon

The New Scientist Reports:

The US military is funding development of a weapon that delivers a bout of excruciating pain from up to 2 kilometres away. Intended for use against rioters, it is meant to leave victims unharmed. But pain researchers are furious that work aimed at controlling pain has been used to develop a weapon. And they fear that the technology will be used for torture.
The capacity to deliver a wap of pain to a group of people from a distance of 2 kilometers without the use of a proyectile may prove disturbing to some.
