But you would think somebody would have caught it on their cellphone, don’cha think?
Not necessarily. I haven’t delved into the circumstances, but got the impression this claim involved a barked insult in passing, not an extended confrontation. Having witnessed (admittedly, many years ago) jerks doing exactly that type of thing, I find it at least plausible. Also plausible that she is outright hoaxing to “make a difference” by exposing racism she “just knows” abounds but is being hidden, or that her brain heard what it wanted to hear to validate her expectations.
