No doubt there are people in California who want to have MJ (and many other drugs) decriminalized while at the same time prohibiting the people at large from exercising their right of selfprotection ~ just like the gun laws out there.
The MJ campaign is just another step in the plan to make California safe for the criminal classes of the Western hemisphere.
So you will subvert the division of authority and responsibility laid out in the Constitution for our own good. Again.
