Judge Patrick Field called Daniel Harris, 19, "highly dangerous" and a "propagandist for an extremist right-wing ideology"

"You were in close touch with other right-wing extremists online and there can be little doubt that you shared ideas between you"[…]
Harris was found guilty in December of five counts of encouraging terrorism and one count of possession of material for terrorist purposes, for trying to make a gun with a 3D printer

The judge at Manchester Crown Court in northern England sentenced Harris to 11 and a half years, with a further three years under supervised probation

The court heard that the teenager from Derbyshire in central England posted videos online for over a year, from the age of 17

Harris reportedly posted under the name BookAnon on a platform called World Truth Videos

His videos were shared by self-declared white supremacist Payton Gendron, who has pleaded guilty to murdering 10 black people[…]
Prosecutors said a link was also found between Harris's videos and Anderson Lee Aldrich, 22, the sole suspect in a shooting in a gay nightclub in the US city of Colorado Springs in November 2022

The prosecutor said that one of Harris's videos was posted on a "brother site" to one showing a livestream of Aldrich before the attack[…]
The court was told one of Harris's videos, titled "How to Achieve Victory", called for "total extermination of sub-humans once and for all"

Another video paid homage to the white supremacist murderer of British MP Jo Cox in 2016

He also praised the Australian white supremacist who murdered 51 Muslim people in New Zealand mosques in 2019 as a "saint"[…]
Harris was placed in a government deradicalisation programme, but Counter-Terrorism Policing detective inspector Chris Brett said he continued to post extremist material

"Harris was ultimately deemed not to have been groomed, rather his provocative words and inflammatory films were potentially radicalising others"
