I mean this is exactly the reason why they won't want to put Trump in jail - so that it doesn't turn out like in Korea. After all, where you can put one president in jail, you can put a next one in jail too.
I mean, yes? Where you can put one president in jail (for trying to demolish democracy and establish oligarchy/autocracy), you can put a next one in jail too (if they try to do the same)
This is called upholding the constitution and it’s fundamental for a democracy. If you say president is immune, you get current US.
