The term "innocent bystander" refers to individuals who are present during an incident or event, but have no involvement in it. They did not cause the situation and are not directly affected by it. In other words, they are people who happen to be at the wrong place at the wrong time. These individuals may experience emotional distress, physical harm, or property damage as a result of being near an incident that was out of their control. The phrase "innocent bystander" is often used in criminal investigations when describing witnesses who were not involved in the crime but saw what happened.
