LOUISVILLE, Ky. — On June 11, just 13 weeks after Breonna Taylor had been shot dead by Louisville police, her mother stood on the steps of Louisville Metro Hall to praise the city's passage of "Breonna's Law." The ordinance banning no-knock search warrants was a testament to her daughter's "agenda to save lives" as an ER tech who dreamed of becoming a nurse, Tamika Palmer told a crowd of supporters. "I knew she was destined for greatness," she said, her smile beaming. "She's showing it. She's showing it." In the eight months since, versions of Breonna's Law, have been proposed in cities and states across the U.S. — from Wisconsin to New Mexico, and from Columbus, Ohio, to Pomona, California.
