We were asked why we did not include a summary of the Chemical Safety Board Report in the Afterword to our book. The answer lies in the schedule for the book. The CSB report was issued in early 2016, at which time we were well into the production process and we chose not to disrupt that process to incorporate newly released material, especially since our study of the CSB documents revealed no new evidence which would alter any significant aspects of our analysis.
We also had questions with the CSB report which would take many months to resolve. So we decided that rather than include a somewhat hurried and possibly misleading summary we would postpone consideration of the CSB report until the next edition, should one be forthcoming.
