Since there is no controlling case law on any of these issues, and no statutory guidance as yet enacted, all of these issues are subject to interpretation. The parameters of amendment 20 are literally whatever the judge and/or jury decide they are at the end of a trial. This provides fuck-all actual guidance of course, and also means the result as applied to a particular fact situation will be completely different by geography and even before different judges in the same district. Even charging decisions made by DAs in different districts will be completely different. I think I prefer the certainty of continued illegality without the pretense of official sanction.
