Even if the state legislature does pass laws to try and protect us from legal action by LEO it still won't protect us at the federal level. I'm one of those 10th Amendment believers and believe that if the feds do step in again there needs to be a class action lawsuit filed by the injured parties on the fact that the feds do not have jurisdiction in these kinds of matters unless it crosses state lines.
And if the initiative passes that is probably what is going to take place. The feds will not be happy that cannabis is legalized as a recreational drug. But people have to make a stand. We can't just continue to allow the feds to roll over us.
