It seems part of your comment may be alluding to today, the anniversary of the Itaewon crowd crush.
I want to emphasize that Halloween was not commodified or appropriated to express dissent here. It was a very localized phenomenon primarily celebrated in the traditional "foreigner neighborhood" near the now mostly defunct yongsan army base.

The crowds were also something of a concern. Maybe half a million people would practically flood whole neighbourhoods. It was kinda scary. Police used sharing bikes to cordon off certain areas…
