Hm yeah, you're probably right. I guess it's naive or wishful thinking to think that the current violence and injustice is anything but calculated. The impact prohibitionist propaganda has had on the perception of drugs and drug related issues in the popular consciousness surely makes things easier nowadays though... I mean, the work there has already been done. Drugs are bad, mmkay, and so is everyone who does them.
This idea is so pervasive it's become unconscious. I believe the main narrator seemed to be well intentioned and was not trying to hide the injustice in any way - but I remember him saying something like "yaba, a form of methamphetamine that has devastated the region..." - really? THAT'S what's devastated the region, not the myriad of other social problems that preceded it?
I'll admit - I don't know much, if anything, about the history of Bangladesh - but it seems self-evident that for such a situation as the one depicted to even arise, there are already some problems, for sure.
