It was during the part of the trial where they talked about possible racial discrimination in the camps, which would lead to more charges due to the camps being part of the DOJ. Marco was talking about Abby, and how she’d been forbidden to marry Edward Yazzie.
Prosecution: Mr. St. James, please tell the court what Mr. Yazzie said to you about his courtship with Miss Calhoun.
Marco: Edward said he’d asked for Abby’s hand after meeting her on a courtship swap. Abby supported the match. But her dad said–
Calhoun: My daughter would never have wanted to marry a redskin!
Marco: Shut the f*** up, you liar! They were going to run away together! The only reason they’re dead is because of the JM-104! You’re responsible for her death!
Fortunately, there was no mistrial. Marco’s comments were struck from the record (”speculation”), but Calhoun certainly hadn’t helped himself by shouting about Edward being a “redskin.”
