Laser gun sights light from all can penetrate through the a piece of iron.So the laser point can shoot through coins.
Horse puckey. There is no laser gun sight that can even go through a piece of paper, let alone a piece of metal.
I think perhaps he meant that you can shoot holes in a piece of iron, then shine the laser through them. I'm always a bit suspicious of new posters providing helpful links to sellers in their messages. I'm willing to give this one the benefit of the doubt, but based on some Googling and checking laser forums, "tmart" doesn't sound like a particularly reliable supplier. Shop carefully.
If true, why the need for the firearm and ammunition? Just point the laser and the perp has a hole in him.
That's what I was thinking. Have you ever seen a cop light up a perp with his gun's laser? Not only does the laser not burn a hole through the guy, it does not even make his clothes smolder. Now if the cop pointed the laser at the perp's pocket I'm sure the laser would burn right through any coins the guy had in his pocket.
Here is interesting read on now cancelled YAL-1 Airborne Laser system "The ABL does not burn through or disintegrate its target. It heats the missile skin, weakening it, causing failure from high speed flight stress. The laser uses chemical fuel similar to rocket propellant to generate the high laser power. Current plans call for each 747 to carry enough laser fuel for about 20 shots, or perhaps as many as 40 low-power shots against fragile TBMs."
