Better question: "How are blown to sheet dead arabic guys going to service 72 virgins?"
Not only that, but what do you suppose they could do to the candy undetected to taint it? I suppose they might try using hypodermics to inject poison/anthrax/smallpox into the candy, but they'd have to be very careful not to leave an obvious hole.
Oh boy. Let's hope this is just a coincidence. Maybe the men were just trying to restock their convenience store in a hurry, and didn't have time for the niceties of a valid card? Not that we shouldn't try to track these guys down, but perhaps the simpler explanation in this case is the correct one.
With 70 virgins each, it can be done.
By moving it back into stores owned by a Moslem terrorist. Or walk into a regular store and put bags of candy back on the shelves.
... by returning the tainted candy to the store for others to buy. I live near one of the stores where this alledgedly happened. The candy was returned AND PUT BACK ON THE SHELVES!
