Make no doubt about it that I am a very strong advocate for the 2nd Amendment but assertions like this support the liberal. What if I am your neighbor and I am distilling saran gas, breeding a biological disease, growing anthrax or building a suitcase atomic bomb? One might argue that I am within my right until I use this weapon (arms) but where is your act of redress after I use such weapons?

You would have to be extremely wealthy, and your house would have to be a high-tech fully equipped laboratory, in order for you to build even just one of these weapons. If you do have such resources, no law is going to stop you from building such a weapon anyway.

After you use your weapon on him, he will be dead, just as if you shot him. You can't kill everybody though, so there will be somebody left to arrest you.
