"Lincolnshire Police said John had first come to the attention of counter-terrorism officers in 2018 after he wrote a letter entitled Eternal Front - Lincolnshire Fascist Underground.
He was arrested in January 2020, and later charged with offences under the Terrorism Act, including possessing documents on combat, homemade weapons and explosives.
The force said John had become part of the Extreme Right Wing (XRW) online - a term for activists who commit criminal activity motivated by a political or cultural view, such as racism or extreme nationalism.
He amassed 67,788 documents in bulk downloads onto hard drives, which contained a wealth of white supremacist and anti-Semitic material.
One of the hard drives was found hidden inside a sock when police searched his home, officers said.
He was convicted by a jury of one count of possessing information likely to be useful to a terrorist and cleared of six other counts of the same offence."

We've had decades of experience of terrorism, partly funded and supplied by Americans; that's why we prefer not to take unnecessary risks. If you don't do anything to attract the attention of our anti-terrorist police, you won't get arrested for owning a copy of the Anarchist's Cookbook. Fact.
