No, I may not have been clear. Of course he wouldn’t. I was thinking of someone who is a criminal of some sort who has information about the crime. Eg: someone who deals with stolen property. *IF* something was stolen that night and this witness unwittingly purchased the items to re-sell them. They can identify the source of the goods, but if they go to police they risk exposure of their criminal enterprise. They might be a jeweller, with a legitimate store. Only they deal with questionable items sometimes. Source: I grew up next door to family related to organized crime. Their cousin had what seemed to be a legitimate jewelry store. Turns out it wasn’t.
