Fox just showed a video of her walking alone on a sideway and it looked to me that she walked off the sidewalk and had to correct. It gave me the impression she was rather drunk. I could be wrong. Ill rewind it and watch again.
when you're in fight or flight mode you are also not too coordinated. combined with being a bit buzzed I think stumbling off a curb is not a big deal. she didn't fall or lose her balance. when you are drunk you are not aware of danger and you walk slower. you think everyone is your BFF. I think she was maybe buzzed but she walks and runs a straight line quite quickly. I cannot run drunk at all. I expect cell phone guy was enjoying the chase and the fear he caused in her. typical mid 30-40 year old white guy psychopath.
