The biggest issue with this myth is that you know where the person who gave you the tainted candy lives. Yes, you get a bag full of candy from different places. However, some kids only visit a few homes. It would not be hard to track who was giving out what.
You're far more likely to get tainted products from a supermarket. Someone can taint them and leave the store without anyone being the wiser. Or even swap out pre-tainted products in the store.
