This weapon has been around for a little while now. Or rather the aiming system has, there is nothing new about the gun its self at all. The system shown in the video goes for about $20,000 dollars ad can be purchased now by civilians.
Do you hunt? Do you eat meat? Or are you a vegetarian?
This weapon with the right ballistic will take down an animal instantaneously. Un- like a cow, which smells the blood of the cows who just got their brains smashed in at the slaughterhouse, and lives its last moments in terror. The animal this rifle kills (used properly) dies without a moment of pain or fear. The system in the video also reduces the chance of mistaken targets (other hunters, protected animals, and in combat; civilians among others)
Hunters to not enjoy when they miss and their target suffers. Neither do the solders I know.
The only disgusting thing is war its self. But war is a certainty for every generation. It would be wrong not to develop precision weapons for war, just as it would be wrong to practice 18th century medicine knowing what we know today. Weapons like this shorten the suffering of people and animals, by shortening the length of the conflict.
But it depends like in all things who is holding this weapon, and why.
Do to the nature of the system, they will never end up in gangland, or a school shooting.
