it's not just population density in a strict geographical sense.
let's go back to the days of the frontier; you see a guy with his cart about a mile away, there's nothing else around. you could kill him and take everything he has, but maybe you are not going to do that. you're gonna go get yourself some land, grow horses, farm corn, and shoot deer. you'll have freedom and that's all you want.
if i look out of my window, i don't see any deer, or cattle, or hunting game - all i see is buildings and people.
if i want to make a living, it will have to do with interacting with these people, in a way or another.
countries with low density population tend to have less crime for this very reason, a whole subset of crimes depends on having a lot of people nearby; to be a career scammer, forger, guy who steals cars, guy who buys stolen cars, guy who breaks up stolen cars, burglar, drug dealer, cigarette importer, you name it - they rely on having "customers".
when you're on the range, if you only have four neighbors in a 10 mile range, you won't make much out of being a career criminal - you got cattle rustling, murder, and bank robber - that's bout it.
they had nearly no law presence in the old west, you'd think there would be more murder, but no.
it's a mentality that derives from having no opportunities except interacting with people, that causes crime to spike. that's why gun ownership is more problematic in high density areas while it's less of a problem in rural areas.
also, when you live in rural areas,
you actually have to shoot thing, be them rabbits eating your garden, or the occasional angry moose.
and besides, we're not perfect .. if anything, we are stupid, irrational animals. waving a gun is like waving a spear is like beating your chest: you're just trying to get the other alpha to stay away from your kids / food / water source .. but if they come closer, you'll have to use it.
the more people waving guns at each other, the more guns get waved, the more guns get used - it's arms race escalation, not something i just made up. it leads to war - surely you should be able to see the parallel that the same on a smaller scale leads to crime

second, having more guns leads .. having free, uncontrolled guns that are seen as toys (not by everyone, but by many)

leads to more crime.
you can't just keep ignoring the statistics and their correlations that
everyone else in teh world has studied and which have always led to the same conclusion, with subsequent application, and corresponding effect - "reducing guns" reduces crime.
many americans seem tied to the idea that they must preserve the constitution at all costs; that if an article is in it, preserving it is the duty of every citizen.
dude, what you MUST do, is come up with a reasonable set of laws that allows you to live; that's why the constitution was drafted in the first place. because otherwise, "it's written in the constitution" starts to sound a lot like "it's written in the bible".
