In a situation where a person has been caused damage, it is forbidden to inform him of the perpetrator’s identity unless there is a reasonable chance that this will serve a constructive purpose. The fact that one personally observed an improper act does not automatically justify informing the victim. If restitution seems unlikely and there is no possibility that the victim will unsuspectingly be vulnerable to further harm, nothing positive will be accomplished by telling the victim who was responsible; to reveal the perpetrator’s identity is to speak rechilus.
