And besides which, that is merely a claim by the defense attorney.
The defense attorney also claims that....
"The McMichaels claimed that they began pursuing Arbery in their truck because they thought he was a burglar after a spate of thefts in their area, and that he attacked them when they tried to make a citizen's arrest. [Travis is] being attacked and overwhelmed by Ahmaud Arbery's strength. And he has to either fire that gun or lose his life at that point"
The problem with this fairy story is that the incident is on video; we've all seen it, and we know that is not what happened. That the defense attorney is even attempting to spin the incident this way shows how desperate he is, and how little credibility can be given to this other claim about Roddy Bryan lying about the N-word.
Certainly their Facebook posts that contain frequent use of the N-word and other racist slurs, show that such an act would be completely in character for them - that makes Roddy Bryan's statement more likely true than not.
