Not necessarily!! Some jurors have been spotted rolling their eyes - probably bc they can feel his frustration!! Maybe they recognize Juan wants to cut through this pointles bull***** and get justice! After-all, if JA didn't put everyone through the damn ringer with all of her stories of what happened & just owned up to it, no-one would be here now dealing with this!!
Until you've been to trial yourself, let alone sat up there at the table with your client(s) and attorney(s) and gone through all the motions you may want to remember you may not know what works best... I'm not an "expert" but believe me, some jurors appreciate Juan's technique.
