Unless he is granted a full pardon for all potential charges related to past offense, it will hang over his head like a noose. The fact this is not on the forefront of everyone tweeting #FreeRoss with hopes Trump commutes sentence (NOT a pardon) tells me people have learned nothing from the pain of people whose names they've never heard of, but without whom, they'd never know of Bitcoin.

Would a federal pardon matter if a state charges? The governor of that state would have to pardon, I think. I wonder if "all potential charges" was explicitly stated in the pardon, if Maryland then could not charge? I don't know how these things work, but this has definitely been on my mind.
