the trial judge improperly allowed women to testify about allegations against the ex-movie mogul that weren’t part of the case.
Well, yeah, that's a pretty major problem. If they're bringing in allegations that aren't part of the case how is the defendant supposed to defend himself against that?
Everyone getting angry about this as a miscarriage of justice, I agree, but direct that anger at the judge and prosecutors who screwed it up so badly. Echoes of Cosby getting off due to a prosecutor making a stupid deal, or OJ getting off because the police apparently tried to frame a guilty man.
