Lucky him, getting a choice to work for the New Order. I'm gonna drag him down to the basement and pump him full of cyanide to see how people deal with both pain and poison.

Jokes aside, the whole "being part of information warfare, learning of a plot and then leaving" thing basically sounds as if he is getting away with learning some of the militaries deepest secrets. New Order will, without a doubt, be watching the information that flows in and out of the grid. If this conspiracy is as big as you say, it would not be out there for any old person in the DPS to find. And even if it was, they would have their best guys focussing their attention on it. The best case scenario is they find out, he is tracked down and has his brains blown out by New Order operatives. Worst case is they drag him away and torture and experiment on him until they are either satisfied and kill him, or he dies under the strain. Being let go from something like this, even if he no longer is part of the military, is not something that happens without a high up or twos design. With the way New Order is, with everything that is going on, it just doesnt make sense.
