The one time I broached this subject with a friend who was also a parent, the predictable response received was "But what if it happened to your child?" Which, you know, misses the point completely. [But I let it go.]
Schneier on Security: Parental Fears vs. Realities:
"...the top five worries of parents are, in order:
But how do children really get hurt or killed?
Homicide (usually committed by a person who knows the child, not a stranger)
Why such a big discrepancy between worries and reality? Barnes says parents fixate on rare events because they internalize horrific stories they hear on the news or from a friend without stopping to think about the odds the same thing could happen to their children."
