Why DJH wasn't at the top of the list as POI all along, I'm not sure, ...
Maybe he was? I know I've made this point before but, we know this not by words but by behavior. LE and the Courts sealed documents related to this POI from the very beginning (along with two others who were not long after ruled out). So, why continue to seal this until 2015 unless he wasn't at the top of their list? I think he was. Their interest was clear by their actions, and their desire to keep that interest confidential is also self evident it seems.
