What did Ingram Say?
If something is true, then it is a fact.
No. Gravity, for example, has caused objects to fall to earth based on their mass for as long as observances have been made. It's true that when you drop something, it will fall. That doesn't make it fact. Just because it has been observed to occur in all previous cases, doesn't make something fact, hence the theory of relativity which describes gravity.
It's not a fact because we don't know with 100% certainty that the words were directed at Payton. It's looks 99% certain that they were, but without Ingram saying "stop running that ******** ****, [Sean]" or saying later in a press conference, "yeah, I told Sean to stop running that ****", it's not a fact.
Words have meaning. Fact does not mean what you think it means. What you are describing would more closely resemble a theory. Without objective direct correlations between Ingram's words and Payton, it's just a theory. What we have is subjective proof. He was looking at him. Payton calls the plays. Both of those instances require us to infer that he's talking to Payton. If it was a fact on its own merit, inference would not be necessary.
