The crazy is strong with this one, I can tell.
Yes, but enough about yourself, we're talking about weapons here. I've taken the liberty of correcting your spelling errors.
1) Yes, I can do whatever I want with it but no I can't? Make up your mind. I have certainly not pointed a gun at anybody, not even figuratively. I have a device that prevents you from winning a fight with me.
Well, if I have a gun drawn and aimed at your head, you certainly can't win any fight with me, either. The problem lies not in the fact that you have a device which prevents me from winning any fight with you, but in the fact that the device also threatens everyone within range. A bomb is not a shield.
2) I'm incentivizing. You're the one calling it terror. I'm just carrying a big gun. There could be some collateral damage, I agree, but the mugger could miss me while shooting at me and hit the nursing home behind me, so that damage could happen anyway.
Assuming that the mugger was using a nuclear hand grenade, yes. But he's not. He's using a firearm. Use proportional force, ie another firearm. You're not just carrying a big gun. You're pointing that gun at everyone in range, and saying, "Better not fuck with me, or I'll blow you all away!"
3) The park shooting wasn't my example actually, but I quite enjoy it. How can you fire a rifle without handling it in the open first (or waving it around if you will)?. So I can wave a gun around, and if someone kills me for it they will have to pay my family restitution? Let's just pretend you didn't want to ban me from my gun-waving earlier.
And the park shooting guy, he's preparing to shoot through the park right now, and I see this as a threat to my family and friends still in there somewhere, and he's adamant about shooting right now, assuring me that he will pay restitution if he hits anyone in my family. Can I use my own gun to shoot him before he hits anybody, or do I have to wait until somebody dies?
It's public property. That's where the problem lies. It's his land too. Get your friends out of his shooting range, if you feel they're being threatened.
4) So a gun is fine, but a loaded gun isn't? Again, I'm not harming anybody. And if they feel that I'm somehow threatening them I'm cool with them pointing a gun at me. No biggie. They might perceive me as a threat, but that's not my problem. And anybody in that room with a gun could also be perceived as a threat.
Again, a loaded gun is fine, as long as it's not being pointed randomly at people. A nuclear device is fine, as long as it's not armed. Armed is not loaded. Armed is hammer cocked and pointed.
I also happen to have a few asshole cousins. They also love nuclear bombs and they hate your way of life. They will do anything to hurt you. Sorry about that. But I'm sure the nuke they're buying has a legit purpose.
A tool is a tool. A nuclear bomb is a tool to make a very large explosion. That explosion can be used for good (say, asteroid mining) or evil (blowing up a city). Guess which category your retributive vest falls under.
