Two of those show a positive correlation, for periods ranging from 9 to 13 years, between increased arrests and increased demand for mj. The other shows a positive correlation between decreased arrests and decreased demand from 1979-1991. Given those correlations, one can't very well make a case for saying increased enforcement efforts caused a reduction in demand.
You pull these out for no reason -- other than you selectively picked certain times where my statement wouldn't appply.
You meant to show causality with your figures, correct? If so, then the examples I gave tend to refute your claim.
Yes, but not with just arrests. That was your idea and I stupidly played along. No more.
