I read some where that law enforcement (especially riot control) are using lasers to turn the air leading to a target to plasma (super heated gas). Since plasmas are better conductors than gasses an electrical shock ranging from a painful sting to a lethal charge is then "fired" at the target, could this be possible, is it being done and if you were to make one what MW and nm laser would be capable of this and could a marx generator supply the charge ?
