Police to test laser that 'blinds rioters' (UK article) (Can U.S. be far behind?)
The laser, resembling a rifle and known as an SMU 100, can dazzle and incapacitate targets up to 500m away with a wall of light up to three metres squared. It costs £25,000 and has an infrared scope to spot looters in poor visibility.

A Home Office spokesman said scientists at its Centre for Applied Science and Technology believe the use of lasers "has merit" and that it will be piloted by at least one police force. However, they will have to be satisfied the technology does not cause long-term health damage before it can be approved by the Home Secretary.
Other technology being studied includes 'wireless electronic interceptors' that can be fired a greater distance than Tasers, and long-range chemical irritant projectiles, the newspaper said.
The Metropolitan Police is exploring the possibility of buying three water cannons at a cost of £4m. Currently the only police force in the UK to operate water cannon is the Police Force of Northern Ireland (PSNI), which has six. Scotland Yard is also increasing the number of officers trained to fire plastic bullets, as a direct response to the riots.
