A protest that started peacefully eventually turned violent, leading to the arrest of several demonstrators. During an interview at the police station, a 24-year-old male gave the following statement: "Everyone sort of erupted and I got caught up in the moment. I stopped thinking and never really considered what I was doing. I guess I got carried away with the group."

The young man's statement best describes which phenomenon?

Which of these groups would we be most likely to experience deindividuation?
