I have no idea if he is who he says he is but I think you have to remember that he is very new to being a public figure and speaking out about these types of things. Hoagland and Bob Dean for example, have been in the field for a long time and along the way have developed good speaking skills and therefore come across with much more force and charisma. It usually takes people a while to get comfortable with public speaking (especially about such sensitive subjects) and many people are terrified even of the thought of speaking in public.
This interview was certainly not very informative but I would encourage people to give him a little more time before judging him in order to allow him to collect his thoughts and get use to sharing this information publicly.
