Should the news media link the murder of Jo Cox with the Brexit campaign?

This article is by Dr Bart Cammaerts, LSE. The media have diligently and extensively reported on the just concluded trial of Thomas Mair, who murdered the pro-migrant Labour MP Jo Cox just before the Brexit vote. Across all media platforms her murder tends to be reported as the act of an isolated, disaffected and unemployed Nazi-loving nut-case, an attack by a domestic terrorist cell comprised of one person. Mair is, in other words, depicted as a rotten apple in an otherwise healthy barrel.
