That appears to have been a petit mal seizure. Know what it looks like - a good friend of mine’s wife has epilepsy. Seen it many times.
My mom had those..It looks like the person is daydreaming..
After watching the video several times, I’d have to agree.
She was just staring and seemed startled when the black guy rushed up to her side. Then he pats her on the shoulder as if to comfort her.
They must be well trained to detect them because they were on her in a heartbeat. Clearly nothing new to them.
The disconnect in her eyes and the inability to speak during that interval is very suspect for sure!
