[UV laser taser]
> This sounds like a great way to make the taser more of a longer range
Yes, and it should be easier to engage multiple targets too. No more (single use) wires, just point and fire 'till your out of juice. Quick reloading shouldn't be a problem either; just slam in a fresh magazine-shaped battery and you're ready to go. Very neat.

That would be nasty indeed. Perhaps the good old single-heavy- needle approach (used to sedate wild animals) is still the best. Or, as a compromize, you could fire 2-5 medium-sized projectiles at once.

Hydrophones? I suppose you don't mean the notorious head drip method (allegedly also very effective)?

Interesting! I suppose you could make projectiles that do more or less the same. Make the gun air-powered and it won't even be considered a weapon in many countries. Perhaps one of the most sophisticated methods to kill someone is by means of electromagnetic pulses. I once read somewhere that "the passage of approx. 100 milliamperes of directed frequency through the myocardium can lead to cardiac arrest and death". If this effect could be achieved at some distance, and with fairly quick and reliable results, you'd have quite a weapon. No traces, no sound, no evidence. A big version could wipe out hundreds (or more) of people at once. Move over, neutron bomb; this weapon could leave cities perfectly intact while "neutralizing" their residents.
