University of Delaware urban sociologist Dr. Joel Best has investigated this for years and says that it is completely bogus.
"Halloween is supposed to be a scary holiday. We don't believe in ghosts and goblins any more, but we do believe in criminals," Best says.
Best says the notion of poisoned candy really picked up steam only after the Tylenol poisonings of 1982.
"That led a lot of commentators to speculate that there would be a wave of copycat poisonings after that. There was no such wave," Best says.
