School safety

Alex Tabarrok at Marginal Revolution posted a fine letter that he wrote to the principal of his son's high school. I liked it enough that I forwarded it to the principal of my daughter's elementary school.

Lurking in the background is the question that Alex implicitly raises, which is why parents in general are much more freaked out about the safety of their children than they used to be, when in fact their children are far safer than they used to be. Social science should have an answer to this, but so far as I know it does not.
