I, for one, support Charlie Shrem...
EVEN IF HE IS INNOCENT.
I would hope you support him if he's innocent

It's a stretch to call him a political prisoner though. He wasn't out doing political activism and suppressed and arrested as a result.
While I agree the war on drugs is a sick joke and it's really fucked up when the head of a bank can get caught laundering money for cartels and only pay a fine while another guy is facing a long prison sentence potentially.
With that said, he's a smart adult and if the emails he exchanged are accurate then he was fully aware of what he was doing and as a compliance officer he knows the risks full well. I may not like speeding laws but if I go over the speed limit everyday I'm not going to complain too much if given a ticket because I knew the risks and took the gamble. I would instead work with lobbyists/politicans to get speeding laws changed instead, that's far a more productive means to a problem.
Who knows if Shrem was a guy doing this for moral views or just to get rich quick, I haven't heard anything suggesting he was doing this for some moral or political reason, just as a means to get rich quickly. Best of luck to him though during his trial and I don't think anyone should suffer prison for non violent crimes. If guilty and he know he was breaking the law then I say fine him, maybe some prohibation, and move on...no need to put him jail, that doesn't help anyone in society.
