All I'm saying to people is, don't stress about it, the odds are pretty remote. Some folks I know get really, really worried about things like stranger abduction, out of all proportion to the actual risk.
(Actually, I should mention that the odds are pretty remote in Australia. I knew a lady in NZ who'd emigrated there from South Africa, after having to shoot two guys who were trying to kidnap her children from outside their school. YMMV depending upon where you live. A good hint is that if you find yourself needing a handgun on the school run, it might be time to move.)
