Five ex-police officers have been charged with second-degree murder after beating Tyre Nichols, 29, who was black, during a traffic stop in Memphis, Tennessee. He died three days later. Nichols’ death has sparked protests and fresh calls for reform of the police in Memphis and nationwide. Over the past years, the US has been in the spotlight for police brutality. Public outcry against the murders of George Floyd, Breonna Taylor and Rayshard Brooks - to name a few - at the hands of the police led to Black Lives Matter protests across the globe.

And is reform or a more radical rethink needed?
