it is difficult to watch. right now, we don't know where tmz got this video. it does corroborate a lot of what we heard from officials as to how the attack played out. some of the things that stand out is you see people just casually walking. there's nothing really that stands out about esteban santiago specifically as he's moving around. he's nondescript, until the moment he reaches in his waistband. one thing that stood out to me, is the moments before you see him walking in the frame, there's children walking right in front of him. from one moment to the next, the expression on his face seemingly opportunity change. he then pulls out the weapon and starts shooting the team nearest to him. again, with a blank stare on his face. at one point, he seemsly crouches and starts running. and you see people, as you said, fred, start to go to the ground. people are crouching behind baggage carts and finding any way they can to hide from this man. we don't know how tmz got this video.
