Caveat to the phrase—when other factors could be involved.
Here's one where I think correlation and causation is a factor—for the past twenty years SSRI drugs have been prescribed and more used. The upswing in mass shootings isseems to be related here due the related timing and the side-effects on the label state these involve "psychotic episodes of violence and suicide." Even terrorist training camps have used drugs such as amphetamines to jack the killers up.
