    we may argue that even a low success rate is acceptable if it
    prevents a child from being murdered. The twist is that the
    issuance of Amber alerts is often too slow to thwart these 
    extremely rare abominations.

    ¾ of children who are both abducted and murdered are killed
    within the first 3 hours of the kidnapping.

    on average, children who are recovered after what police deems
    a successful Amber alert are found 15 hours later.
