Borders cancels mob book signings after threat

The Chicago Tribune reports:

Two Chicago area book signings scheduled at Borders Books involving former Chicago mobster Frank Calabrese Jr. were canceled after an anonymous threat, a Borders official said today.

“We can confirm that our Oak Brook store received a voice mail threatening violence should Mr. Calabrese’s scheduled book signings take place,” said Mary Davis, spokeswoman for Borders. “Given the controversial nature of the content of the book, we viewed this as a legitimate threat. The safety of our employees and our customers is of the utmost importance and that is why we made the decision to cancel Mr. Calabrese’s events.”
