Whatever Matt said that seemed to be outrageous regarding the Horizon spill, he is off the hook with me.
I had corresponded with the man by email over the years and had a pleasant lunch with him in Boston some years back so I can't say that I knew him well, but what little I did know led me to believe he was a courteous gentleman with a keen interest in his personal intellectual pursuits.
I am saddened to hear of his passing.
