You cannot ban guns in the United States. No laws in effect have been effective in stopping gun crime for the simple and obvious reason that criminals don't care about laws. Many who engage in mass shootings have no intention of surviving the experience, so they have no reverence at all for some crime they might commit. You can't prosecute a corpse.
It is so infuriating to suffer the stupidity of the left time after time. The issues are not in dispute by any logical, thoughtful person seeking the truth. Chicago as an example of the leftist utopia that it has been for a century demonstrates that all of their collectivist impulses toward immigration, gun laws, taxes and education prove the fallacy of their arguments. But, collectivists never acknowledge the facts or the truth, they spend all of their time in the future, where everything is better and all of their fallacious beliefs have resulted in an utopian existence. The reason the future is so alluring to them is the present, their present, the present created by their unwillingness to accept some obvious truths is hell.
So, after Las Vegas, we go back into the reactionary mode of writing laws and banning things that if it worked, Chicago would not be the disaster that it is. A good model to counter the Chicago example is Houston. As far as population, percentage of minorities and crime go, they are essentially the same, but where gun laws go they are completely different. There are no gun shops in Chicago, but in Houston their are over 1000 places to purchase weapons. In Chicago, there is no concealed carry law, whereas in Houston there is. In Chicago, homicides run around 500 per year; in Houston there are roughly 200.
But, look at any honest statistic you choose and you will find the same thing. Guns reduce crime. Guns reduce murder rates. Guns are used, by the Center for Disease Control numbers, 240,000 times a year to ward off intruders or prevent crime. That is the number of times it has been reported to officials and does not account for the times when an individual either drew his weapon or revealed its presence to an offender to stop a crime from occurring without any further action. It is obvious to anyone not afflicted with the collectivist disease of fact-blindness outcome-denial that an armed, or possibly armed individual is too great a risk to a thief or murderer to engage.
That is the problem, the collectivists aren't interested in the truth or outcome, they seek only the disarmament of those they intend to oppress. Those hundreds of millions of guns out there in society have thus far prevented them from being able to pursue with vigor their vision of a communist state in America. They have worked their way through education, government agencies and the media and turned those entities into collectivist havens with the intent of turning public opinion away from the individual rights we enjoy. They have diluted the Constitution through government policy with the ultimate goal of discarding it as soon as possible. The only stumbling block is the Second Amendment and they are coming hard to get rid of it. They don't care how many false flags they have to put up, how many lives they have to destroy, because like any good communist, the end justifies the means.
Nowhere in history have the collectivists bothered to count their corpses. The only ones who have ever been interested in that tally are the historians of the West and they are determined to eliminate them.
