These evil strangers...

In a Wall Street Journal article entitled 'Stranger Danger' and the Decline of Halloween the following paragraph is to be found:

That was a wacky idea, but we bought it. We still buy it, even though Joel Best, a sociologist at the University of Delaware, has researched the topic and spends every October telling the press that there has never been a single case of any child being killed by a stranger's Halloween candy. (Oh, yes, he concedes, there was once a Texas boy poisoned by a Pixie Stix. But his dad did it for the insurance money. He was executed.)

Even if the March to Keep Fear Alive is over I guess we can still fear things. Did that mean it succeeded? (And why is shipping for the March to Keep Fear Alive merchandise restricted to the US?)
