The "right" to bear arms must of necessity (logical necessity) include the right of the individual to their very own B-52 bomber (see image). Mines, poison gas, and anti-tank weapons as well. After all, it does say, "the right of the people to keep and bear arms"; it doesn't specify which arms, so presumably it includes all of them.
Oh, but don't worry. I'm sure that we can trust civilians with their very own arsenals of WMD's, especially if they don't have a criminal record, and imposing access restrictions on those "law-abiding citizens" would just mean that the thugs, criminals and gangsters would be able to obliterate entire nations.
Whilst a gun may need a nutcase to pull the trigger to wipe out (for example) an entire classroom, without a gun the crazy killer in question wouldn't be able to kill as many as quickly and as efficiently. THAT is the difference a gun makes, and no, there are no good reasons to ban kitchen knives as well, or cars (and don't be the person who reveals his/her utter stupidity by asking that question here). Kitchen knives and cars serve a useful purpose; guns do not.
And I don't want to hear whingers complain that I'm not a U. S. citizen! So what? That's irrelevant to the case, the argument being made here.
Note: To any moderator who sees this, I am not "trolling" here. My question is perfectly legitimate, and I'd like an answer to it. I say this because one of my recent questions was removed, and then restored, because it was (kind of) similar.
A person with a gun who just has to pull a trigger will kill many more within a shorter amount of time than someone with just a knife (or their bare hands).
