&gt;&quot;The greatest risk of severe injury or death occurs from impacts to the head, face, or neck of the intended target or a bystander, &quot; Widder says. &quot;The use of more accurate weapons with disciplined fire can substantially reduce the likelihood of this unintended consequence.&quot;<p>giving that the weapon has great precision, adding a camera and a bit of software able to recognize when it is pointed to a face would allow to block the shot if it directed at a face. Though one can imagine a protester wearing several &quot;V&quot; masks everywhere over his&#x2F;her body as the counter-measure...<p>On the other side, why all this new, and thus expensive, weapons when there are good old paintball guns easily and cheaply available? In the same way, based on laser rangefinder input, the firing controller can easily automatically adjust the firing pressure and timing so that to achieve the optimal velocity at the target.
