You should note that when police act in high tensity situation they subdue everyone most of the time. Not like in movies. Cause they can hurt themselves move where they shouldn't etc...
As a law abiding citizen, I've never been involved in such a situation, you know, how would I know that
Jokes aside, story-wise I don't know about an electro laser pistol (at least a DF powered one), the lore presents the laser pistol as a difficult achievement for the science team, while on the other hand the electro laser is that heavy for a reason it need more powerful systems (I'm not a physicist, but I assume the ionising laser pulse doesn't require much more energy than the standard issue laser, the problem, I think is the actual electric discharge) so if the standard issue laser pistol was such a struggle it seems like a electro laser pistol would be a no-go.
Which leaves us with a purpose built "crowd control weapon" which doesn't seem something an UN sponsored PHALANX would be developing or the pre-invasion, low-power, one-shot models implied to exist in the electro laser research report
Aside that there's the ever present problem in this project: we lack artists, there's no one to come up with the required models, effects and such assets.
But sure, someone bring a good artist and writer to make the needed assets and write the tech reports —including a reasonable explanation for PHALANX researching/adopting this weapon — and we'll see what we can do
(as long as all those assets and lore are open source licensed of course)
