A member of the crew reported it.
FYI .... yeah, they knew it was a pull cord. But that knowledge doesn't necessarily imply that it wasn't intentionally tied a certain way with racial intent.
In hindsight, yes, it was not a racial knot. But the questions is:
In light of the NASCAR flag tensions, and
In light of the BLM affiliation to the driver, and
In light of the recent nationwide protests and riots,
Was it reasonable for someone, at that time, to suddenly notice the knot, and notify authorities as a precaution, at least?
FYI, this currently is not comparable to Jussie's clown show.
