I think the State’s impeachment of Bradley might have remained in the State’s back pocket, until the Judge ordered the in camera review, at which point using bogus privilege claims to hide certain inconvenient facts had failed. Given that Bradley’s testimony had been friendly to the State, the ruthless Miss Cross “had to” destroy Bradley’s reputation to remake him into a hostile witness, giving the judge an excuse to suppress his testimony.
Whether the judge falls for this is doubtful, but ... politics.
No one seems to have noticed this, but Cross’s accusations have implications: “Wade’s law partner Bradley had sex with an employee and gave her a large amount of money; therefore, Bradley was forced out of his law firm and his testimony can’t be credited.” But Fani Willis was having sex with her contract employee and funneled large amounts of money to him. Miss Cross impeached Willis and Wade by analogy, and implied they should be forced out of office too.
Great point
