Yeah my coworker tried showing me this. There's no audio and nothing to indicate what's actually going on. I don't know what trials in the DPRK like, but do they really look like this? The audience looked like they were in a stadium or auditorium or something. For all I know this could be a theater and everyone on that stage is an actor.
I don't even think watching dramas are illegal in the DPRK lmao. I'm pretty sure nearly everyone in the DPRK watches pirated media they buy on USB drives and no one cares.
