The only problem with your analogy is that the Chinese authorites look after their own, not foreigners. Also, Frankie boy has likely paid off everyone of import, or would were any actual trouble raised. Truth be told though, I think it is obvious the authorities could give a lick about how he operates, and will likely only go after someone who isn't "paid up" if you get my meaning.

No, the only way to protect ourselves against Frank the snake and his multiple personality disorder is to seek him out and keep posting warnings, where ever he might be.
