Chris, your own video here shows the item hitting the back of her leg a couple of inches above the hemline. It flashes by fast, but look at exactly the 20-21 second mark with the screen enlarged.
I am watching it at .25 speed from 19-21 seconds, and I cannot see anything fall outside of her pants leg. Nothing.
I’m not trying to be controversial either, I can’t see it. Perhaps you can, but I cannot.
It’s too bad someone didn’t pick up whatever it was for further investigation.
