a) instantaneous: OK. That is true. For a localized spot on the retina. A drop of acetone hitting your eye could be worse.
b) faster than the blink reflex: Yes, if you aim it right through your pupil and then switch it on. Any other way might trigger the blink reflex before the main mode enters your eye
c1) Infinite range: Well, because maybe 15m it will be bigger than the pupil of the eye, so any further distance will reduce the power by r^2. At 150m its the level of a typical laser pointer at short range
c2) c1 requires a steady hold. Without a tripot, at longer distances the entering time of the eye by the laser is likely to be limited in the ms region, rendering it harmless
d) reflections dont matter: If you use polished, flat metal or a mirror. Any other way will fasten the dispersion enormously.
Yes, it is NO toy, and it should NOT be placed in the hands of children (as well as adults who think everybody can be used as "self defense weapon").
But everybody is working with MUCH more dangerout stuff everyday (especially since the unlimited range is bullshit). And what i find even more bewildering this agitation by americans who do not seem to have a single problem with having a gun instead?!.
By creating that image of the death ray thats more dangerous that a gun you will only draw the wrong people to such stuff. The ones that are bored if its not even sorching white paper and than try to aim it at their buddy.
