Well if he is being protected by the military then you are now putting yourself at risk by making this post. If there are any merits to your accusation then you should be reporting him to the authorities and not plotting to stalk and criminally harass him. If you want to get this guy without becoming a criminal yourself then I would suggest using his own hubris against him and get him to expose himself. Um...that came out wrong. I mean get him to make a mistake that produces evidence against him. If you feel the need to have a back alley "chat" with a baseball bat just do it and don't advertise your intentions on reddit. If you haven't been paying attention, there are highly organized groups of these people who have tons of money and hold powerful positions in society. They are very dangerous and will ruin your life and reputation first if you try to cross them.
