A creative enough person could kill another without a weapon, and a weapon could be made from many ordinary household objects.
But this gun is only a gun, an unliscenced, unregulated gun that has proven to be less safe than an actual gun.
I see no problem which what the police are saying here, but it is a very difficult thing to regulate.
There's no need to regulate. In fact killing another person is already illegal.
But, you don't understand! This is completely different! This is killing somebody with something built with plans downloaded over the internet!! On a computer!!!
Works for US patent submissions, right?
What in the world are they gonna do when the next-gen version of a firearm is invented and the plans widely released/distributed, and that can be made cheaply, quickly, and simply with common materials, and possibly doesn't even use "bullets" as we know them at all? Maybe some sort of electromagnetically-accelerated "micro-needler" or "micro-flechette" weapon, or something accelerated-plasma-based? "Give me a phased plasma rifle in a 40 watt range."
I must say I have a fundamental problem with a government declaring that, under threat of death or imprisonment, I'm not allowed to defend my family, my community, or myself, and with being denied the current and essential tools for that defense. Police do not protect. They draw chalk outlines and *hopefully* find and arrest the suspected perpetrator(s) after the crime/violence has already occurred.
The right to personal self-defense and to the commonly-employed and current tools used to exercise that basic right to defend your life, that of your family, and of fellow-citizens, are primary and essential human rights. Without them, all other rights are meaningless. How does one exercise a right when dead? How free can one be if they have no legal ability to defend their right to continue living?
To remove the ability of people to defend themselves and their families is to make them a slave to anyone stronger, multiple attackers, or anyone who is armed. It gives the elderly, older children, and women a force-equalizer against a large and powerful male attacker. A rape whistle does no good when you're grabbed by the throat and being strangled. Likewise, the police are no help when a deadly threat is imminent and officers are minutes away at best.
I'll just leave this here. http://www.youtube.com/watch?v=pa-lNiIDsFM
