Various writers have suggested more or less plainly that the Patriarch was involved in the crime. Sokrates does not say so plainly, but he implies it and adds a solemn moral reflection. As a matter of fact, not only is there no sort of evidence that he had anything to do with it, there are positive reasons for knowing that he had not.
While some writers have suggested that Socrates was involved in the crime, Socrates himself does not explicitly confirm this. However, his silence and a solemn moral reflection suggest a connection, while evidence points towards his innocence.
