I was kind of thinking the same thing.
IMHO the whole Manning espionage affair was a larger conspiracy and an Obama Administration inside job with high level Obama people colluding with Manning to collect Top Secret information for Manning to leak
Obama gave him a sentence commutation to keep him from exposing others in the conspiracy
I was just thinking the same thing or perhaps a state could charge him with screwing over all of us who live in various states. This way some liberal President someday can’t pardon this cretin and would have to do time entirely.
