Farr, in an affidavit, said he was afraid that the police would arrest him on drug charges. In exchange for the money, and to avoid jail, he agreed to set up Banks, he said, persuading him to drive to Dallas to get a gun. Prosecutors allowed Cook and Farr to lie in court and never told jurors that their information was false, the Supreme Court found. Cook denied on the stand that anyone had helped him with his testimony, and Farr said he had not been paid for his help in the case. During closing arguments, Elliott told jurors that they should believe the two witnesses.
