Surprised they responded at all since it was such a poor response. Ultimately they are saying he should have gone through legally channels even though of course doing 0 would have yielded 0 results, because he would have no proof. If he disclosed any confidential information he would have been arrested. So there are no legal channels he could have taken. Coming back or turning himself in won't do anything except allow the US to silence him, send him to jail where he will mysteriously be killed or such. Like all the men and woman before him who fought authority or the church he would ended up being written in the histories some day as a hero. But will be a long time before there is another time distance for the government to be able to admit that.
