The testimony of Witness Eight suggests that she didn't seem surprised at the notion of TM starting a fight with GZ. Could MOM/West pursue that further if they call her back to the stand? It would seem that if TM was in the habit of getting into fights with strangers, it would be at least plausible that he would have instigated the fight in this case, which should in and of itself imply reasonable doubt.
I believe Witness Eight said that “TM would have told me if he was gonna fight” which means he probably did tell her he was going to fight but she just didn’t tell “us”
I am glad that she mentioned the “Creepy Ass Cracker” description though. That was good of her to share that with us.
