Yes, as of now he has lost all his benefits. He is on active duty but is not being paid. His sentence was for six months in prison, loss of all pay and benefits, and dismissal from the Army (that's like a BCD, except they don't give those to officers; we get "dismissed" instead). According to the article, he is currently petitioning via the appeals process to get some of his benefits back, although he has acknowledged that his appeal probably won't get past the initial process. According to the article:
"Realistically, I understand that a very small fraction [of appeals] get reviewed and a smaller fraction get overturned or anything," Lakin said. "But the appeals attorney has some issues he wants to bring up."
My guess is this this is somewhat like the April Gallop lawsuit in that the lawyer is the one attempting to get information that has already been deemed inadmissable in court into a brief, or something similar. Lakin has already admitted he was wrong to do what he did, back before he was sentenced.
The thing I find somewhat untenable in all of this is that his license to practice medicine has not been suspended or revoked. He is required to report that he was dismissed from service to the board, but he can still legally practice medicine. I suppose his politics don't prevent him from being a decent doctor, but I can't help but want the man to actually suffer the kind of difficulty in finding a job that a soldier given a BCD would after their discharge. It just doesn't seem fair to me that officers get it easier than soldiers do.
Lakin also has a new cause, apparently; the article indicates that he wants to try and review the cases of several soldiers who are currently serving sentences in Leavenworth, because he feels they may have been wrongfully imprisoned. Judging from my own experience with the military legal system, I think the likelihood of that is much less than it would be in the civilian legal system, but I admit, IANAML (I am not a military lawyer). My personal take on it is that Lakin merely wants to stay in the limelight (I wouldn't be surprised to hear of a book deal coming his way) and is seeking to use the other soldiers to do that, which I find to be reprehensible. However, if he does manage to find someone in Leavenworth who was wrongfully imprisoned, I for one will be grateful to the man; no one should ever be imprisoned wrongfully.
