Which is fine if you're considering general law making - the thing is that it doesn't matter one hoot to a parent, Ms. Dugar's mother say, that the chance of a car stopping at the side of the road and snatching your child is vanishingly small. If it happens at all it happens too often.
It's no comfort to know if you've been incarcerated for years with the threat of sexual abuse, torture or death hanging over you that very few people get kidnapped really.
It does matter to a parent, because parents (and people in general) should worry about things in proportion to their likelihood to happen and their impact. But we are irrational creatures, and we don't.
Yet people go all ga-ga about guy in the beat-up car trolling through residential neighborhoods to entice kids into his car with promises of candy. This image is largely a modern-day boogie-man. It does happen, and it is a tragedy. But there are MORE children that are raped by a parent/sibling/babysitter than there are by complete strangers.
