Hi Bill, Just a quick note to say that I'm sorry that our idea for the criminal behavior work last year did not work out.
When I got the various results and charts that your staff compiled I was not able to see a way to further develop the analysis or link it to our prior work. Then, I think the project gradually ended. Perhaps if I had been able to formulate more constructive questions it may have had a better outcome. Anyway, I hope you are doing well, and also congratulations on finishing the MBA. I hope we get a chance to catch up at the upcoming classification meeting.
