You definitely get better protection if you use your credit card. Maybe it depends on the bank, as I've only had to do it 3 or 4 times in my life, but they've always stood by me, even in less obvious situations than the linked post.

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
