Sounds like the same kind of guides that were being printed in the West https://twitter.com/TurnerMarko/status/1066830331288973314
From the (Western) guide:
Skinheads: Enjoy fighting
Rude Boys: Are enthusiastic vandals
Punks: Out to shock through their appearance and behavior, have anarchist leanings
Roots Boys: anti-police
We don't really know what the archives of western states would show if subjected to comparable scrutiny (to the limited extent those archives were made available, e.g. in Switzerland, they show an appalling amount of surveillance, though a comparatively limited amount and degree of repression).
You're right, the sentiment persists, but with different words, which was my point.
