Unlike West Virginia University, which accepted $1 million from Bob Murray of Crandall Canyon mining disaster fame, Miami University has agreed to return somewhere in the neighborhood of $5.2 million donated by Minnesota businessman Thomas Petters, who was found guilty last week of running a $3.5 billion Ponzi scheme.   Most of these funds were going to create the John T. Petters Center for Leadership, Ethics and Skills Development.  ”The university has no interest in keeping money that Mr. Petters obtained by fraud or deceit,” said Miami University’s President.  I guess it’s hard to create a center for ethics with ill-gotten gains, even if the irony would be delicious.
