Its always the Paulbots in denial about Obama being BY FAR the most liberal of any sitting president on cannabis since long before prohibition was ever considered. It's only so they can push their Koch endorsed POS supply-side trickle-down ass hole candidate who they believe is holy and beyond reproach. They tout these big numbers of arrests and leave out the fact that nobody is actually doing any time over these petty crimes and the only arrests are of non state compliant and multimillion dollar commercial grows, dispensaries and so forth. They also leave out that more progress has been made in the last four years against prohibition (one third of the country) with openly operating dispensaries and reputable doctors signing prescriptions, than at anytime since ever. So yes, more arrests, because more activity.
Be state compliant and don't run a massive commercial cooperative and you will be fine, just like Obama says.
It is still illegal and the president can't change the law, he can only enforce it, or in this case not so much--see Holder memo.
