You’d have thought that shock-jock Infowars loudmouth Alex Jones might have learned to keep his trap shut after being humbled in the courts over his diabolical claims that 2012’s Sandy Hook school shooting was one big fat hoax. Of the new mayor for Derry, he recently raved that ‘the World Economic Forum is now installing invaders as mayors in Ireland just like in London.’ Given that he’s a far-right conspiracy theorist, it should come as no surprise to learn that Kenya-born Lilian Seenoi-Barr is the first black mayoral appointment in Northern Ireland’s history.

Silence is not an option for him, obviously, and despite The Truth Vs Alex Jones laying out his Sandy Hook shame bit by bit, he will probably only feel emboldened by it. Jones craves attention so no doubt all he will see across its two hours is his ‘brand’ being highlighted. The rest of us will observe a man whose worldview is so utterly blinkered that he spouts off about left-leaning plots wherever he looks. Most disturbing of all, he actually has the ear of Trump.

What also comes across in this documentary is the dignity and resilience of parents who lost their children (aged six or seven) in the most horrendous manner imaginable, when heavily-armed 20-year-old Adam Lanza entered a school building one December morning to perpetuate carnage on a devastating scale. Within hours of the tragedy, the ever courageous Jones was on his ‘show’ spouting drivel about it being a state-sponsored false flag event designed to ‘take our guns away’ (12 years on, how has that turned out?), later denouncing grieving parents as being ‘crisis actors’. When Jon Ronson included him in his 2001 documentary series The Secret Rulers Of The World, Jones came across as almost likeable, a little cranky but largely harmless. In a pretty packed field, he is now arguably the most dangerous man in America.

The Truth Vs Alex Jones is available on Sky Documentaries/NOW from Thursday 13 June.
