Also remember Annabeth's and Reyna's conversation when they met at Charleston. Even after they found out Leo was being controlled, Reyna admitted to Annabeth that she would be taken back for a trail (even if the outcome was already decided before it even started). Also, Nico wasn't there at the time so his testimony wouldn't be helpful. Hazel's might, but she is somewhat of an outcast at camp and she (along with Frank and Jason) spent a large amount of time in Greek company, meaning no one would listen to them. I'm not sure how, but Athena's statue seems to be the only way to stop the fighting and no one knows how it even works
