PBS “Frontline” is once again setting its sights on an issue close to TV news. Last time it was the News Corp. hacking scandal, this time it is the fallibility of evidence in crime investigations. There is a seriously newsworthy element however, in an interview with Jose Baez, the lawyer who helped Casey Anthony get acquitted last year.

“She had photographs of her and her child, and a network paid us $200,000 so we could mount a proper defense,” Baez said.

That network was ABC News, which ended up changing its policy on licensing material in exchange for interviews in part because of the Anthony imbroglio.

Baez essentially argues in the interview that the money provided by ABC News gave them the resources to shed doubt on the forensic evidence being used against Anthony.
