He used two examples of the kinds of cases where he would consider it, both mass shootings — the 2012 shooting of 26 people, including 20 children, in Sandy Hook, Conn., and the 2017 mass shooting on the Las Vegas Strip in which a gunman killed 60 people and wounded more than 400.

He said at the time that he took a short break after Musk reactivated the account of Sandy Hook conspiracy theorist Alex Jones, then discovered that he didn’t miss the platform “at all.”

He had a fascination with mass shooters, idolising the perpetrator of the 2012 Sandy Hook killings in the United States, and his internet history included him watching extremely violent content.

One of those spree shootings was at Sandy Hook, the Connecticut elementary school where 26 people were killed in 2012.

The 19-year-old was arrested in the hours after the murders, but told police of his "Friday the 13th" plan to kill 30 pupils at St Joseph's Catholic Primary School in an attack more deadly than the Sandy Hook shootings in America in 2012.
