We live in a clown world where you can be a citizen of another country and the US can get you arrested and extradited there. They can also imprison you for alleged crimes committed against its monetary policy which is another joke of a law.
Think about a scenario where you live in some remote country and one day local police arrests you and says you're going to the US because you did something that's forbidden there and they want to prosecute you. You don't even speak English and don't know US laws. This is how dumb this can get.
I'm not going to pity Roger because he did some shady shit in his life with that bch - sv fork and spamming bitcoin to show BCH is cheaper to transact with, but he doesn't deserve prison.
