Taking back what the scammer took from a community member

One of the community member has been scammed. It is clearly his responsibility to be in trouble, but a person is usually punished when the fraudulent activity is proved with fiat currency. I am kind of curious whether this applies in crypto, so I am requesting the force transfer from the scammer's address to the community member.

His claim on fraud is written in google docs, and you can ask questions by commenting on the document.
