An odd rant. The judge in question appears to be an alcoholic, and came to the court drunk. Surely this is professional misconduct (and to my mind warrants firing), but it really doesn't justify the author's charges of system-rigging. Seems to me that Clark is trying to mislead people into thinking that Pollack was under the influence of e.g heroin. Pretty despicable.
Also, the smallest bit of Googling shows that Pollack heads was responsible for the creation of some sort of special "marijuana court" which expressly sent users to rehab, not jail.
I don't know much about this Clark guy (girl?), and I agree with some of the points in the article, but he/she seems pretty close to a flat-out liar.
