In my opinion Manna should go home. Although, he's not a good guy I feel like he did his time for the crimes he was convicted for. As far as how the government accomplished the conviction, well if you sleep with dogs you're going to get fleas. Some only believe in the constitution when it fits their narrative, As far as planning on killing the Judge and others, well without some kind of physical evidence like an audio recording planning the murders I will never believe that to be true. If it is then Manna isn't as smart I think he is/was.
