Step-by-step explanation:
Without additional context, it is difficult to determine the speaker's intended meaning. However, the phrase "I know it wasn't just a horse that went crazy" suggests that the speaker is referring to an event in New Orleans where a horse behaved erratically. The speaker may be implying that there was something more to the event than just a horse acting out, and that there may have been external factors or forces that contributed to the horse's behavior. The speaker's statement suggests that they have some knowledge or insight into the situation that is not immediately apparent to others.
