I've been busy with some events and haven't been able to keep up like I should and this might already have been covered (forgive me, if so.)
But watching the smidgen of the video they chose to share. The first thing seen is the kids picking up the papers. The 1st man in the video enters from the right side of the screen. It appears as if these papers are placed in a "bread crumb" fashion to lure the two toddlers. It is a possibility that in the seconds before the video starts, man1 is the guy who put out the papers and engaged the toddlers in the luring game. The second man2 enters from the gate across the way... not the same place that the first man enters. He stops and says something to the children, as evidenced by them stopping and listening to him. Then they merrily head back (Cupcake even leads the way) in the direction they (kids) came from. Did man1 lead the toddlers out as a "viewing" for man2? Was man2 watching from the area he came from? Was the path of papers leading away, but in front of, the gate purposely? Have the rest of those papers been recovered and what is the nature of them? At that particular moment, there was no wind according to the past weather observations. Were these papers planned to carry out this event or picked up rashly? I think I read s ok somewhere (help me out with the link) that LE said it appeared to possibly planned only 10-15 min prior to the abduction. Could this be because of this paper trail set up and where said papers came from?
There's a reason LE only chose those particular seconds, I think. They know the man who took her (man2) but they want to know who laid out those papers (man1.) The surveillance captures him doing that and they chose not to show it to the public.
