Amazon and the Bernardo book: Have they no decency?

The book attributed to the execrable Paul Bernardo is gone from the listings of Amazon Canada  where it was being hawked for seven or eight dollars. But the question remains: How in the name of God did it get there at all? What miserable weasel at Amazon actually entertained this outrage?  Bernardo is locked up and will die in prison for his unspeakable crimes. Does Amazon have absolutely no decency?
