Well, I don't like to spread hysteria either, however, one of the stores in question is very close to me. I am waiting anxiously for a good, innocent reason for why boat loads of candy were returned by Middle Eastern men with fake membership cards, and why this candy was then put back on the shelf. There could be a perfectly innocent reason. However, I find it odd that they haven't gotten to the bottom of this yet. Of course, if I didn't live in the area, or have kids, I wouldn't worry either...
Where are you getting this from?
That is not what the story said. It said they bought $35,000 worth of candy, not that they returned it. Any store that puts an opened bag of returned candy back on the shelf is begging for a lawsuit. If that candy contained smallpox and hundreds, thousands, or tens of thousands died from it, the resulting lawsuit would wipe that store chain off the face of the earth.
Trick-or-treating people you know, who have kids of their own, should be safe. Don't go anywhere else.
Perhaps they realized the jig was up on the poison the candy idea, and that Middle Eastern types with lots of candy was not a good idea, so they were taking it back...never mind. ;)
