While her specialty remains thrashing the school board, teachers' union, and classroom chaos, this "Pitbull in Pumps" (a nickname from her days in Tulsa television) has branched out recently. She's looked into everything from failing police radios in Miami Beach to prescription drug prices to medical fraud. For her fans, Jilda knows how to cut to the chase. To the retired dentist whose "resonator" had no tangible medical value, the relentless investigator asked, "Have you cured AIDS?" Does she have detractors? Of course, and she's proud of the long list. "Why do I have to explain it to Jilda Unruh?" one of the teachers' union members demanded of her when she questioned him about his bloated contract. Well, sir, because if you don't respond, she might just sink her teeth into you.
