I am just guessing, and I guess a little hoping, that S. Korea has such individuals “on a very tight leash”.

I cannot imagine fewer positions more sought after by a double agent than those working directly inside the intelligence apparatus, as opposed to mere “informants”.

A really paranoid S. Korean could imagine this individual helping to facilitate other “defections” that become not “defections” after all. I’m glad I am not the S. Koreans that this individual reports to. I think I would have trouble sleeping at night.

They are on a tight leash of sorts. He is "protected" 24 hours a day by guards. He is said to be on NK's hit list.

No doubt one has to look out for such a possibility.
