When did they start making commercial charged-particle laser stun guns? Please let me know who makes them so I may purchase one, I’ve always wanted a laser weapon.
As for the Tazers, they are less-lethal, not non-lethal, and I’ve been careful to make that distinction where appropriate. But again, when you take the nightsticks away from cops, when you take the beanbag rounds away and you issue Tazers then take them away, the only other option is what you see here - shooting the person dead.
Your last paragraph is indicative of a training problem, not an inherent problem of the weapon system.
Training problem ~ yup! But you know we hear about a new case of this several times a year, and you’d think even cops would catch on that when somebody is preternaturally UNCONSCIOUS and not moving, that they are already down!
