I don’t see anything...
Further down on the page is another video. Something pops out of her leg area. Looks to be silver in color and some kind of a tube but other than that, it is difficult to tell. What is obvious is the fact that she is not walking on her own but is being physically moved by others into the van. From the buckling of her legs, she would appear to me to have passed out.
It’s a small white something that falls in a split second from an angle upper right to lower left on her lower pant leg. You can only see it because the whatever is white and her pants are dark.
