There are many examples of such people – the friends and family of mass shooters who ignore warning signs of impending violence, the people on social media who encourage potential shooters, the National Rifle Association for pushing laws that benefit gun manufacturers at the expense of shooting victims, courts that have twisted the Second Amendment (which was intended to provide for a well-regulated militia in the absence of a standing army) to mean that anyone can own and carry guns, gun dealers who fail to perform background checks and sell guns to felons and the mentally ill, politicians who bow to the wishes of the NRA instead of their constituents, and citizens who prefer to bury their heads in the sand rather than call for action after another mass shooting.

These people are all responsible. They all deserve to be known as mass murderers.

How else would you describe people who enable more than 3,000 shooting deaths each year, including the deaths of more than 500 children? How else would you describe people who stand idly by while more than 7,500 children are wounded by guns each year? How else would you describe people who ignore hundreds of mass shootings each year, including the 42 that have taken place on school campuses already this year?

How else would you describe politicians who refuse to permit the Center for Disease Control and Prevention to track gun violence along with the other major causes of deaths? How else would you describe politicians who make laws that prevent pediatricians from discussing gun safety with parents; who have made it easy for anyone to own the weapons of war – assault rifles, 50-caliber sniper rifles, semi-automatic handguns, armor-piercing bullets…even silencers; who have refused to pass even the most benign gun safety laws?

How else would you describe politicians and manufacturers who have made our nation the world’s largest weapons dealer – weapons that are often turned on our own soldiers?

It doesn’t have to be this way. Not that many years ago, Australia’s conservative government reacted to a mass shooting by passing laws that banned most gun ownership and bought back guns from its once heavily-armed populace. Indeed, most other advanced nations restrict gun ownership. Even places like Dodge City and Tombstone in the Old West once had restrictive gun carry laws – that’s why historic events like the gunfight at the OK Corral still stand out. They once were far from commonplace.

But, now that nearly everyone is allowed to own and carry guns, gunfights are an everyday occurrence. Though the percentage of gun owners is declining, those who do own them own more guns than ever. These people have an irrational obsession with guns. They justify that obsession by claiming their guns are needed for self-protection from criminals, the government and “those people.” They carry them everywhere. In fact, many are so paranoid, they will not enter an establishment that prevents the carry of guns. But the reality is that guns are seldom successfully used for self-protection. More often, such guns are stolen or used for suicides. They are used in road rage incidents, in domestic disputes, in neighborhood disputes, in drive-by shootings, in theaters, in workplaces and in schools. They are used by the mentally ill, by frustrated loners, by jilted lovers, by angry husbands, by racists, and by rogue cops. They are used to threaten and intimidate. They are even used to threaten government officials who are carrying out their lawful duties.

What can be done to prevent more shootings?

We can start by improving mental health care to help the nearly one in four Americans who suffer from mental illness. We can improve our database of the criminally-ill and potentially criminally-ill. We can pass a law requiring universal background checks. We can require a 30-day waiting period for gun sales. We can make it illegal to open carry in public places. We can roll back our conceal-and-carry laws by requiring gun owners to show a need for a carry permit. We can ban large caliber weapons, such as .50 caliber sniper rifles and all other weapons of war. We can, once again, make the sale of silencers illegal. We can ban armor-piercing ammunition. We can ban large capacity magazines. And we can pass gun laws that are uniform nationwide so that rogue gun dealers in one state can no longer sell guns to residents from other states and other countries.

Finally…and this will be the most controversial suggestion…we can ban the sale and ownership of all semi-automatic guns. After all, these are not needed for hunting or even for self-defense. They are designed to make it easier to kill people. Period.
