IMO, none of the stuff the defense is focusing on or bringing to light is exculpatory or even relevant to whether evidence exists that warrants binding BM over for trial.
Their agenda is twofold. First, to simply to make sure everyone knows that SM wasn’t the saint that media portrayed her as. (I never believed she was. She’s an imperfect human as are we all.) MSM will latch on to the salacious revelations at the expense of the boring but important details that will make the case against BM.
And second, to delay the progress of the PH by using as much time as they can get away with in their cross and by raising topics that they hope the prosecution will spend precious time on rebutting or clarifying.
Judge Murphy is being far too lenient with them IMO. But I trust he is able to sort the wheat from the chaff. It’s still the states game to lose, for sure.
