We’ve been watching many of his rallies folks.
Notice Donald, when the crowd starts yelling he turns around to the people in back of him. Is that just to give the ones in back a look or is this a plan by the USSS? It just hit me...
I've always assumed it was just Trump acknowledging the people behind him. Notice lots of them looking up, I assume to a display screen. Otherwise, they don't get a very good view! I can't imagine any useful security purpose.
