Blaming the victim

Explanation: In terms of psychology, blaming the victim is the act in which victim is accounted for their hardship and suffering. The offender of the crime is not considered faulty for the act rather victim is held responsible due to victim's behavior and actions , persisting prejudice against the sufferer .

As per the case in the question , Martha's friend is blaming Martha for getting mugged and thus, blaming the victim. Her friend is making Martha the faulty person in the case by considering she should have known about risk in walking down that road at night and she stating that she had misfortune.
