The mass shootings that regularly occur in the United States are mostly also suicides.
They are the ultimate “deaths of despair.”
The killers do their shooting in public places and are almost guaranteed to be gunned down in their turn, if they don’t kill themselves first.
They are comparable to the suicide bombers in the Middle East and elsewhere, except that the jihadist killers are sometimes trying to achieve a specific military objective, like the Japanese kamikaze pilots during World War Two.
Among all the rich Western nations, the United States is the only one in which mass shootings occur on a regular basis.
That is not to say that ordinary Americans, and visitors to the United States, are in grave danger. As a risk factor, mass shootings rank far below traffic accidents.
But the fact that they occur says something about our society. For every man (the shooters are almost all men) who kills others and then himself out of rage and despair, there must be a hundred others who feel the same rage and despair and don’t act it out.
Some people blame availability of guns, and I agree it would be better if the government restricted sales of rapid-firing firearms with large ammunition clips and magazines. Casualties from mass killings were fewer during the assault weapons ban, but they still occurred.
Some people blame ideologies based on hatred of black people or hatred of immigrants or hatred of women. But the mass shooters can be of any race, and the percentage of white mass shooters is slightly less than the percentage of whites in the general population.
The killers profess all kinds of professed political and social motives and some profess no motives at all. The only common denominator is that the killers are almost all suicidal men.
Hatred and bigotry have long been motives for killing. The new thing is that the killers are suicidal.
There are ways to commit murder without sacrificing your life in the process. (The methods are obvious, but if you can’t think of them, I see no benefit to society in helping you out.)
I think the root cause of mass killings are feelings of powerlessness and feelings of meaninglessness. Your life is meaningless, so you give it up. But you take others with you, so you do have some power after all.
I don’t have a good answer for this. Calling for a greater sense of community or a stronger sense of values isn’t going to bring these things about. Greater availability of mental health counseling probably would help some, but it won’t in itself empower people or make their lives meaningful.
