To recap what I shared earlier:
The U.S. has higher crimes attributed to guns compared to various OECD countries, and the reason is obvious: more guns, more incidences of crime, etc. involving guns.
The Second Amendment is not about the right to bear arms. That right is part of English common law, which means it doesn't need to be approved by government. In short, the right to bear arms takes place by default, and does not need to be mentioned in the Constitution or statutes.
What, then, is the Second Amendment about? It is not about the right to bear arms. Rather, it is about the need to form well-regulated militias using the right to bear arms as justification. That is why we have the Militia Acts that followed the amendment. The statutes required almost all white, able-bodied males of a certain age to acquire weapons (muskets, the equivalent of assault or battle rifles) and then train with a militia twice a year. The militia is answerable to the POTUS. Thus, the Second Amendment is NOT about a militia that is meant to protect against "government tyranny." It is a reserve force regulated by the government. Subsequent acts made this statute permanent, included African-American males, and called for the formation of a National Guard. Later, conscription was removed.
Thus, the second amendment obliges citizens (at least male adults of a certain age range) to buy assault weapons (or to be provided weapons by the government) and to train with a militia. If it is the National Guard, then training involving armored vehicles, etc., are included. Since such a provision involves training (which is part of gun control), then gun control does not go against the Second Amendment and is not unconstitutional.
In addition, gun control does not violate the right to bear arms. That's because the right to bear arms is one that takes place by default but may be abridged by the law. That's why convicts, for example, are not allowed to bear arms.
Finally, behind all of this is the arms industry. That is, the arms industry profits by selling weapons to civilians. The same arms industry lobbies the government and successfully convinces the latter to set aside gun control. Meanwhile, the same arms industry sells the same weapons (and better) to the same government and profits from that. This allows the police and military to form some of the most formidable surveillance and even prison systems in the world. With that, gun control is replaced by police systems to control civilians with weapons provided by the arms industry that supplies the same weapons (and more) to the police and military.
Next, the same arms industry lobbies government to deregulate arms exports, thus allowing it to profit from sales to many countries, thus making the U.S. the main arms dealer of the world. Why does the government agree? Because the same arms industry sells weapons, etc., to the military, which is used to prop up the petro-dollar, which allows the U.S. to borrow and spend easily. The same arms are used as part of military aid for some countries or even groups used to gain strategic advantages for the U.S., to control particular resources, or even to destabilize various governments. Arms dealers sell to various criminal groups.
Meanwhile, utterly naive citizens think that with small arms they will be able to avoid "tyranny" from a government armed with better weapons, armored vehicles, ground-attack aircraft, missiles, artillery, etc., supplied by the same defense industry that sold small arms to them. Eventually, they face armed threat from fellow citizens, several of which face problems described in this article:http://lewrockwell.com/orig12/shield2.1.1.html
increasing brutality from police and even military personnel, and criminal groups who all acquired armaments from the same sources.
With that, expect more tragedies, more armaments bought and sold not only in the U.S. worldwide (and with that more profits for the arms industry), more lobbying from the arms industry insisting that more guns are needed, more beefed up police and military forces, growing control through surveillance and prison systems, and amplified effects of gun use as social crises worsen.
