Handheld energy weapons

[Rynn]

Active denial systems include microwave pain rays, tasers, high-pitched and subsonic sound cannons, plastic bullets and tear gas - most of these work, but can cause permanent damage or even death. For something more OA, how about an EMP attack on the target's exocortex, or a remote Rewrite attack using neoSQuID technology, affecting the biological brain directly and forcing compliance (or simply causing someone to go to sleep)..

Or a ufog cannon. I can't imagine much more effective at crowd control than firing thousands of cubic meters of cotton-wool like substance that restrains everyone safely.
