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.
“Experience should teach us to be most on our guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” — James Madison
