One week into his term as Franklin County's new prosecutor, Gary Tyack is considering whether his office should take back handling any case involving a former Columbus police officer who was fired within days of fatally shooting an unarmed Black man. "I think for years and years, some police have felt they had immunity as long as they told a story about how they shot someone in self-defense," said Tyack, a Democrat who defeated longtime Republican incumbent prosecutor Ron O'Brien in the November election. "That's what you hear about the cases pending now," Tyack said. "The claim is, 'What I did was in self-defense.' You know, 'His hand wasn't visible to me, and his hand had a cellphone in it, but since I couldn't see one of his hands, I decided he was armed and therefore I needed to shoot.' I'm sorry, we can't let officers keep getting away with that."
