On Tuesday Decarlos Brown Jr was arrested and charged with first-degree murder over the unprovoked attack on Iryna Zarutska on a train in Charlotte, North Carolina, last month.

A video of Zarutska's killing has been circulated - and shared widely - on social media, including by key MAGA figures like Stephen Miller and Elon Musk. It has prompted a widespread debate over crime in American cities, a topic that Donald Trump has cited frequently in his attacks against the Democrats.

Iryna's family have said they are "heartbroken beyond words" and asked people to stop sharing a video showing her final moments.

Justin and Sarah look at how Zarutska's killing, and the subsequent public outrage, could change America's approach to public safety, and whether it might affect the upcoming election in North Carolina.
