‘It’s OK, everyone else is doing it’: how do we deal with role violence on social media played in UK riots?

Among those swiftly convicted and sentenced last week for their part in the racist rioting was Bobby Shirbon, who had left his 18th birthday party at a bingo hall in Hartlepool to join the mob roaming the town's streets, targeting houses thought to be occupied by asylum seekers. Shirbon was arrested for smashing windows and throwing bottles at police. He was sentenced to 20 months in prison.

In custody, Shirbon had claimed that his actions had been justified by their ubiquity: It's OK," he told officers, everyone else is doing it." That has, of course, been a consistent claim from those caught up in mass thuggery down the years, but for many of the hundreds of people now facing significant prison sentences, the defence" has a sharper resonance.
