"Now that my sideboob has gotten your attention, Breonna Taylor's murderers have not been arrested. Demand justice," the Riverdale star wrote in a since-deleted Instagram post. Later apologizing for the post, Reinhart wrote: "I've always tried to use my platform for good. And speak up about things that are important to me. I also can admit when I make a mistake and I made a mistake with my caption. It was never my intent to insult anyone and I'm truly sorry to those that were offended."
