Doesn't matter. With technology trends gun control is never going to work. I know two people who have built multiple guns already by copying designs they found online 1:1. As much as it's fun to say this kind of stuff is rare, it's becoming extremely easy to manufacture guns. (CNC machines are very cheap to own
)
I know someone else with two 50 caliber sniper rifles. He's fired them at the range a few times, but is mostly a gun collector with probably 20 or more guns and rifles. Some people just like collecting them. There's no harm in doing it unless they are stolen, but that is kind of obvious.
We need to probably start targeting the real problems for gun crimes and violence with guns. I'm not sure what that is because I don't really care, but I'm sure it's something psychological or income related. Which probably relates to why some people believe not everyone should be able to own guns, but is more of a quick fix than a solution to the root problem.
