Prison watching

I'm late to the party (it's up to season 5, I see), but I have started watching Inside the World's Toughest Prisons on Netflix.    

I've only watched a few episodes, and so far I have learned:

*  Columbian prisoners may be tough thugs, but they take very good care of their hair grooming;

*  Greenland is trying the "college group house" style of prison running which seems popular in Scandinavia, and it seems every prisoner is in there for some offence related to hashish.  

*  Papua New Guinea treats its remand prisoners to accommodation worse than my local RSPCA gives to its stray dogs.   

Each episode is pretty formulaic, I suppose, and there is something of a "meta" fascination with how the prisoners (and guards) seem to ignore the cameraman, and don't seem to "act up" to being filmed.  (OK, maybe sometimes they do.  But it is sort of hard to tell.)

I still say that the best extended documentary series about an exotic prison, and how it is run, is Happy Jail, about the (formerly) all singing and dancing prison in Cebu.   I strongly recommended it here at the time, and have told people about it in person, but have yet to meet someone else who has actually watched it. My powers of persuasion are obviously low.
