Five years ago I told the story of how some prominent Portland charitable organizations got together a few years earlier to encourage a Person Of Standing to make good on his pledges to those charities. They wrote identical letters to the Person Of Standing, who was an well-known investment manager active in the Republican Party, all saying basically "You made a very generous pledge to our organization last year. If things are tight for you right now, we can work out an installment plan so that you won't be embarrassed about not meeting your pledge." The Person Of Standing, no doubt realizing that the well-connected trustees of these charities all talked with one another, paid his pledges by return mail. He quietly ended his relationships with the charities and moved to Florida.
I don't know whether times were in fact tough for the Person Of Standing ten years ago, but they are now; this week the P.O.S. was arrested and charged with two counts each of securities fraud and wire fraud. I'm guessing that none of the trustees of those charities were still doing business with him.
