Mental hysteria also appears in dominant groups. [fact]
These hysterical cases were sometimes merely wounded and were given over to the police for questioning. The pathological nature of their behavior would not be recognized, and the accused would be tortured for days until the press reported that he had been shot trying to escape while being transferred to another prison, or that he had died of a recurring ailment. In the dominant group, likewise, there were cases of mental hysteria; people would be seized with a collective fear and panicky settlers were seen to seek an outlet in criminal acts. What made the two cases different was that, unlike the colonized, the colonizer always translated his subjective states into acts, real and multiple murders.
