"Death Valley can't be a desert because it rained there today"
Not arguing for or against Montenegrin corruption. Just saying that this incident doesn't contribute to the corruption theory.
I read it as suggesting that Do Kwon’s decision to take up residence there contributed to the corruption theory
"A place with so much corruption" reads to me as a statement of fact, not perception. (Montenegro clocks in between China and Jamaica on the latter [1].)
