I don't know, personally I would rather this pain ray thing than a stick, taser, gas or rubber bullets which is what is being used now. If this thing does no actual damage.
Yes, but we already know from tasers that the less lethal the "non-lethal" agent, the more likely that authority figures will use it unnecessarily.
Also, do you REALLY want the government to have something that can cause physical agony without leaving any mark at all?
No. Only I can be trusted with this sort of SCIENCE.
Not if I get one first!!! 
If you both got one each, then you could fight to resolve silly disputes like this. I'm making one out of an old microwave, a tesla coil, and a satellite dish. I'm going to hook my mobile phone up to it, log on to the net via a Filipino proxy, dial certain telephone numbers, then when the answerers pick up at their end, melt their brains with pulsed microwaves. (On the "quick defrost" setting)
I'm planning a MkII, with an incorporated tight beam E.M Pulse Sniper gun, for low flying aircraft, ground based internal combustion engines, and a directional WIFI Scanner, to pinpoint individual hard drives, at up to 2km away, and wipe them, partition by partition. Then I will be unstoppable. Whatever they send against me, will get blu-screened by my multi-wavelength attack geek array.
I'm going to have a set of lightweight Tailored "Dragonskin" combat fatigues, in case they deploy projectile weaponry, 7 League Boots, a special tin-foil scanning Stealth-Helmet, a Cape, and a catchy Superhero name for myself. I thought maybe Freq-Beast, or the Uninstaller. The US would send the J.L.A to retire me, but they would totally be my Bitches. But can we keep all this between ourselves for now? I don't want to have to go operational until Charlie Sheen delivers my brief. (See, I've really thought about this) David Icke's gonna be my Tech Support, and Public Relations guy, and I thought I'd ask Phoxy to be my Manager and Booking Agent. This time next year, It should be all over, bar the shouting. Then I can unveil my 5 year plan for a Global Utopian Anarchist Supercollective.
BadBeast. Up in your fatpipes, subverting your paradigm.
