While banks are regularly laundering money were not sanctioned to such crime. They prosecute Griffith for simply teaching which isn't even proven yet.
Obviously Griffith is going to be face big players which will probably landed him to jail for life.
I think the guy was noble for wanting to teach others, especially within a country like Korea but really he didn't practice his due diligence and is now facing the harshest of consequences. North Korea has a lot of smoke with the U.S, mainly because of all of the threats they have made to wipe it out. This guy Virgil is extremely lucky that he isn't being tried for treason or worse. He could at least have went to contact Dennis Rodman for help first, they literally love Rodman over there more than Michael Jordan as weird as it may sound.
If they are going to make this crime so big, they can charge treason. He was warned before he flew there.
