That's fair. I definitely think taking a defector from NK 100% at face value is naive. It's difficult to know exactly what happens there, but the stories Park tells are hilarious in their absurdity so it's easier to see and poke fun at.
Not sure how credible this guy's story is, but if he's telling the truth about his position then he probably knows more than Park does. That doesn't mean everything he says is true, though.
