It doesn't surprise me that you completely misunderstood my comment. The thrust of Todd's comment was that we should incarcerate people for future crimes they might commit. As no one knows the future, thus we don't know if Todd will murder someday or whether you will murder someday, we should incarcerate the two of you just to be on the safe side. This is the essence of Todd's advice, and shouldn't Todd live by his own advice, by practicing what he preaches?
