Demand his day in court ? No. Not at all.  

When so many people, proven by you and so many others, so easily siding with the most negative potential aspects of this case - not knowing for sure the facts at all, but easily and willing to assume the most negative. Why try to fight that ? Anyone experienced in confrontation knows you pick your battles. In "mob rule" It's better (safer) to walk away and let the mob have their fun. Trying to stand your ground in a mob (riot) you most likely get beat down. Same here. Just because he may be right, does not mean he could win. Prejudice works both ways...
