Perhaps a more interesting poll would have been about who President Obama should pardon. While I agree that the whistle-blowers should be pardoned, I think it would be much better to pardon all of the people who are in prison for marijuana-related crimes in jurisdictions where their crime is no longer illegal. Seems to me like a form of post facto punishment, and such a blanket pardon would REALLY piss off #PresidentTweety.
You do understand that there isn't a jurisdiction in the USA that Marijuana is legal?
There are a few places where state and local authorities have decided that they won't prosecute, but the federal law is still in place that makes manufacture, distribution, and sale illegal in the whole US territory?
