America is a country in which its citizenry, good or bad, right or wrong, has ownership of an incredible amount of firearms. Not too surprisingly, with so many guns available, in which those firearms are designed in a manner so that they do exceedingly well what firearms do; this country has a crisis in the amount of violence so actuated by those firearms. Those that make insipid statements such as "guns don't kill people, people kill people," are missing the most salient point, that firearms make the killing of people a whole lot easier than it would be, if they did not exist; but they do exist, and they exist in abundance.
The good people that have fought hard in regards to the passage of laws that would stymie the amount of firearms so readily available in this country, have historically not fared very well, which doesn't mean that the battle has been futile, but indicates it is going to be a battle that necessitates looking seriously at all viable options. For instance, tobacco and alcohol are subject to excise taxes, of which, firearms are also subject to excise taxes, but the percentage amount of that tax, should be and must be appreciably higher than the current 10-11%. In other words, the price to purchase a particular firearm is going to be a meaningful factor as to how many or how often or how much a given person will pay for that firearm, and therefore the excise tax for firearms needs to be substantially increased. Additionally, gun shows, need to be subject to a far more withering oversight and to stricter regulations, by appropriate governmental officials, at the place of that show, so that, the comfort level of those so selling firearms at those shows, will be affected in a manner in which the transactions so being made, will not so easily skirt laws that are structured in a manner to preclude firearms, for instance, being sold via a "straw purchase" and the like.
Further, in regards to just about any legal action, money matters. Those that truly want to reduce gun sales and thereby gun violence need to concentrate on the institutions that have the money, and that is the gun and ammunition manufacturers, themselves. No matter what the law has said and no matter what judicial rulings have been made to date, the gun and ammunition manufacturers are neither judgment proof, nor are they perpetually free from lawsuits that will meaningful impact their business profits and their responsibility.
For instance, for years, the tobacco industry was able to win lawsuit after lawsuit, until such a time, that they did not; and eventually they settled for a Master Settlement Agreement to resolve their ongoing litigation issues. So too, gun and ammunition manufacturers can most definitely have their feet held to the fire, and should have their feet held to the fire; for unlike tobacco, which harms the user of it, over an extended period of time; firearms to a very large degree, harms primarily not the buyer of the firearm, but specifically, other people, and can do so in less than one second.
The bottom line is that the Second Amendment is probably not going to be overturned or be re-interpreted in a manner that favors those that support gun control. This signifies that those that want positive change in regards to firearms need to fight such in a relentless manner upon multiple fronts, and that unyielding pressure will ultimately produce a positive result
