M. Tullius Cicero Pro P. Sulla 85

[85] It would appear an offensive thing for him who investigated the conspiracy, who laid it open, who crushed it, whom the senate thanked in unprecedented language, to whom the senate decreed a supplication, which they had never decreed to any one before for civil services, to say in a court of justice, “I would not have defended him if he had been a conspirator.” I do not say that, because it might be offensive; I say this, which in these trials relating to the conspiracy I may claim a right to say, speaking not with authority but with modesty, “I who investigated and chastised that conspiracy would certainly not defend Sulla, if I thought that he had been a conspirator.” I, O judges, say this, which I said at the beginning, that when I was making a thorough inquiry into those great dangers which were threatening everybody, when I was hearing many thing; not believing everything, but guarding against everything, not one word was said to me by any one who gave information, nor did any one hint any suspicion, nor was there the slightest mention in any one's letters, of Publius Sulla.
