You are right, it depends on the card issuer. My friend was forced to pay a large sum at knife point in China a few years ago with his CC, later the CC company told him there was nothing they could do since he personally signed it already.

I have to say it's really not the CC company's problem. Your friend should call the police and ask for the proof document from the police to argue with CC company
