I'm sorry, I didn't bring a copy of the research. I'm sure it's easy to find out, and I have noted in my notes where I got the study. I don't know what percentage were manslaughter, but I agree that I think it's an issue not having manslaughter included, since for many of the cases that we followed, the plea-bargaining process resulted in manslaughter.
