So many problems around cops shooting people and they die. I'm wondering HOW COME noone researched this to create something that can either penetrate glass or not so hard surfaces, and when comes in contact with the skin paralyzes the offender (like the taser, but this can go through things) or simple paralyzes everyone in a radius of a few meters.

Then when the thing settles you go in, get the paralyzed human/animal/whatever, put it in a cage, then wait for it to de-paralyze.

Noone gets hurt, plus the idiot who cannot follow commands won't be killed. Would be so easy.
