In addition to noting that gun control tends to increase crime by reducing the cost of being a criminal (i.e., thugs are less likely to meet armed resistance), Tom Sowell also explains that people who don’t like the Constitution should amend the document rather than appointing ideologically-motivated Justices who ignore what it says.
…there is no obvious reason why issues like gun control should be ideological issues in the first place. It is ultimately an empirical question whether allowing ordinary citizens to have firearms will increase or decrease the amount of violence. Many people who are opposed to gun laws which place severe restrictions on ordinary citizens owning firearms have based themselves on the Second Amendment to the Constitution. But, while the Supreme Court must make the Second Amendment the basis of its rulings on gun control laws, there is no reason why the Second Amendment should be the last word for the voting public. If the end of gun control leads to a bloodbath of runaway shootings, then the Second Amendment can be repealed, just as other Constitutional Amendments have been repealed. Laws exist for people, not people for laws. There is no point arguing, as many people do, that it is difficult to amend the Constitution. The fact that it doesn’t happen very often doesn’t mean that it is difficult. The people may not want it to happen, even if the intelligentsia are itching to change it. …As for the merits or demerits of gun control laws themselves, a vast amount of evidence, both from the United States and from other countries, shows that keeping guns out of the hands of law-abiding citizens does not keep guns out of the hands of criminals. It is not uncommon for a tightening of gun control laws to be followed by an increase– not a decrease– in gun crimes, including murder. Conversely, there have been places and times where an increase in gun ownership has been followed by a reduction in crimes in general and murder in particular. Unfortunately, the media intelligentsia tend to favor gun control laws, so a lot of hard facts about the futility, or the counterproductive consequences of such laws, never reach the public through the media. We hear a lot about countries with stronger gun control laws than the United States that have lower murder rates. But we very seldom hear about countries with stronger gun control laws than the United States that have higher murder rates, such as Russia and Brazil.
