The killing of three girls at a summer dance class in England a year ago Tuesday, by a teenager misidentified as a migrant, triggered days of street violence directed at newcomers and minorities.

Prince William and the Princess of Wales have carried out their first joint public engagement since the end of Kate’s chemotherapy by meeting the bereaved parents of victims of a stabbing rampage in the seaside town of Southport.

The people of the English town of Southport have come together for the first of the funerals for three girls murdered during a Taylor Swift-themed dance class.
