It’s not a conspiracy theory if it’s true.
Watch the video full screen.
1. She appears to be leaning against a bollard to steady herself. A woman is very near her and appears to be steadying her.
2. They van arrives, the large black man opens the doors, then turns to her. He places his hand into her underarm to take hold over her arm and to assist her into the van.
3. As she straightens up from the slight leaning position, her legs buckle at least twice and her head makes an odd movement to the side.
This is the most telling part of the video that she is having a serious medical issue.
4. As they move her to the van, she looses ability to stand up completely. The curb aggravates the situation. Seems she did not even know it was there. If not for people holding her, she would have hit the ground.
