A member of a British far-right messaging group who called for a synagogue to be “firebombed” was sentenced on Wednesday for sharing a video on how to build a replica machine gun, Sky News reported.

James Farrell, 32, of Glasgow, was a member of the extremist Oaken Hearth chat group, where he shared antisemitic, neo-Nazi and racist posts, according to prosecutors.

The group spoke in positive terms about far-right attacks, including the mass shootings at two Christchurch, New Zealand mosques in 2019, of which Farrell praised. He also wrote of his approval of the attack by Norwegian neo-Nazi Anders Breivik in 2011, in which 77 people were killed, and applauded the 1995 Oklahoma City bombing committed by Timothy McVeigh.

Members of the group shared antisemitic and pro-Hitler propaganda, according to prosecutors, with Farrell reportedly stating at one point: "It's about time someone firebombed a synagogue."

The prosecution said that the extremist Telegram channel, which the defendant joined in March 2021, had been infiltrated by an undercover police officer.

The judge said that Farrell, a former security guard, had not shown remorse for his actions. "As the criminal justice social work report states, you continue to adhere to your far-right wing views.”

Farrell pleaded guilty to a breach of the Terrorism Act but said that the video on how to use a 3D printer to make a replica of a MAC-11 machine gun was an “edgy, cool video.”

On Wednesday, the Glasgow High Court judge sentenced him to two years and eight months behind bars.

The judge said that by posting the video, Farrell made it “directly available to extremists and potential terrorists and encouraged or induced or assisted them.”
