I don't know how commong this is, seeing that this is the first trial I really follow, but Juan Martinez has my absolute admiration for not using any kind of notes during his closing argument.
I haven't seen either of the opening arguments, but what with all the clinging to the podium and the paperwork on the podium that the Defence has shown throughout this trial, speaking freely, determinedly, calmly and without having to refer to any kind of notes shows absolute competence, and I think the Jurors will notice that, consciously or unconsciously.
