Yesterday's daily ethical transgression--Lottery Director Dolan's distribution of tickets to a state trooper--was discussed and my sister, the artist, referred me to the work of Mark Lombardi. [1]
It's how conflict of interest makes for slippery slopes. I hope that I don't offend any of the wrong people by mentioning the reference.
