M. Tullius Cicero Pro A. Cluentio 108

[108] O, the singular innocence of Oppianicus! when in the case in which he was defendant, those who acquitted him are supposed to have had some ulterior end,—those who postponed their decision, to have been cautious; but every one who condemned him is esteemed virtuous and firm. 39
  These things, though Quinctius agitated them, were not proved at that time either in the assembly or in a court of justice. For he himself would not allow them to be stated, nor indeed, by reason of the excited state of the multitude, could any one stand up to speak. Therefore he himself, after he had overthrown Junius, abandoned the whole cause. For in a very few days' time he became a private individual, and he perceived too that the violence of men's feelings had cooled down. But if at the time that he accused Junius he had also chosen to accuse Fidiculanius, Fidiculanius would have had no opportunity of making any reply. And at first, indeed, he threatened all those judges who had voted against Oppianicus.
