Guns are for protecting citizens from their governments (and other less serious things). So I don't know of a better way and I do not fancy genocide so hell yea I like guns. We are still going to want guns among us, it is a human right to benefit from our technology.
So, for this reason I like gun purchases to be completely private. It may not be obvious but background checks are a bad idea too simply because your trying to impose stringent requirements on otherwise free people. This leads to the need to enforce hard to enforce laws. Lets remind ourselves, if a free person is really too dangerous to own a gun, they are too dangerous to live among us and own bomb making material, dangerous chemicals, purchase or grow virus, own knives, own forks, own spoons, etc... Background checks send people away from well known public places into private especially when they are a easy target to put people on gun lists. If records are kept they should be kept by the buyer and seller. Additionally constitutional carrie is important. Your constitution is the gun permit.
Finally, last but not least gun training. Gun training is the easiest thing to do and does not prove that you own a gun or put you on any list. Many states are offering free gun training now. From training, to justify the use of a gun (or lethal force) their needs to be a threat of greater bodily harm to yourself of someone else. Greater bodily harm is subjective and decided by a jury but this can include the threat of rape, head-injury, scarring, or death.
