When people are saying the fault is with guns, they are generally talking about this, having access to guns. No one is blaming an inanimate object for existing in a vacuum.

It serves as a counter narrative to a lot of gun supporters talking points: allowing more good guys to have guns will help stop bad guys with guns (it did not), having armed police or security at schools will stop bad guys with a gun (it did not), arming teachers will stop bad guys with a gun (if cops were useless, what would an untrained teacher do?).

It's interesting to see how quickly the "Blue Lives Matter/Thin Blue Line" folks will turn on police officers when they feel they aren't being protected.

Wow.

On one side, I think saying a young man in 2022 is "a gamer" is comparable to saying someone in the 70's "watches TV". It's not a niche thing whatsoever, and gaming is a bigger industry than Hollywood these days, and again, it's worldwide but these kinds of stuff doesn't tend to happen elsewhere but in the US.

On another side, WOW again. Why on earth are those kids purchasing AR-15s? Did they ever tell you any possible reason? 

I just don't get it.

True, so let me clarify.  All of these guys play video games, but the three I referred to as gamers spend virtually all of their free time playing, and are primarily focused on first person shooter games.

One of them comes from a family that owns many firearms, and grew up hunting and shooting recreationally.  The other two have little background with guns.

To answer your question, after playing games where their characters used assault rifles, they wanted to try shooting them in real life.  So they went to a range where they could shoot a variety of guns, including AR-15s.  They all enjoyed handling the guns, so two purchased their own.

No sinister intent involved. These guys only use their rifles at gun ranges, to shoot at targets.  But here is the thing.  It was very easy for them to pass the background check and qualify to buy the guns.

The one from the "gun family" keeps his rifle unloaded and locked in a gun safe.  Ammo is kept in a separate, locked safe.  But the other one doesn't own a gun safe.  I'm not sure where or how he stores his rifle, but anyone who as access to the area where he keeps it conceivably has access to the gun.  That is how Adam Lanza got an AR-15.  The gun belonged to his mother, and she failed to properly secure it.

As I said before, most of the people in the 20-40 age gap I know are gamers and some of them are FPS fanatics but not a single one of them has purchased an AR-15 or been to go a gun range.

Not that they could in most countries, but apart from that there's definitely something going on culturally in the US that just doesn't happen elsewhere.

I don't know how it is in other cities, but a quick Google searched turned up 12 indoor gun ranges in the Las Vegas metro area.  There are several places on the outskirts of town where people can go to legally shoot at targets outdoors.  I suspect we have more than a lot of other cities because many of them cater to tourists; especially the ones that feature AR-15s, machine guns, etc.

There are probably 100+ places in town to legally buy a gun.
