1. Oh yeah, because the symptoms of death from a drug overdose are indistinguishable from the symptoms of death from hypothermia! Idiot.
2. It goes without saying that most of the Occupoopers are hardcore dopers, that a lot of drug dealers are making out quite well peddling their garbage to the protestors, and that many "Protestors" are just there because they know it'll be an easy way to get a quick fix ("Uh, yeah, power to the people, down with the rich! Hey, do you know anyone who could maybe hook me up with a few grams of coke? Um, We are the 99%!"). If anything, combining the lively flow of drugs with the undoubtedly abysmal sanitation conditions of their little tent cities, I'm surprised more of the Occupoopers haven't fatally OD'd yet.
