Pick of the Day

Raising a School Shooter, 10.00pm, BBC Four

The Storyville strand is the home of some of the BBC’s best documentaries – so this should be well worth viewing, though it will be a tough watch.

As the disaster of yet another school shooting hits, some parents are faced with a brutal fact: their child was the one pulling the trigger.

In this powerful and sensitively told documentary, set in America, three parents share their personal stories.

Jeff Williams is the father of Andy, who in 2001, at the age of 15, shot and killed two classmates and wounded 13 other students.

Andy, 25 at the time of filming, is now serving life in prison. Clarence Elliot’s son Nicholas shot and killed his teacher and wounded another in 1988. He too is serving life in prison.

Sue Klebold’s son Dylan was one of the two teenagers behind the Columbine High School massacre in 1999, one of the deadliest school shootings in history. Dylan ended the shooting by committing suicide.

Through the three parents' deeply personal stories and raw, honest testimony, the film explores multiple themes that emerge from terrible tragedies - guilt, failure, responsibility, sorrow, friendship and love.

Don’t Miss

UEFA Euro 2020, 7.00pm, RTÉ2

It’s the second semi-final, as England host Denmark at Wembley Stadium in London (KO 8pm).

Given their home advantage and ability to keep a clean sheet, England go into the game as clear favourites. But Denmark will be the neutral’s choice – for obvious reasons.

It would remarkable if the Danes won the competition, given the near tragedy in their opening game, when midfielder Christian Eriksen suffered a cardiac arrest. Can the fairytale continue for the land of Hans Christian Anderson?

Darragh Maloney presents, with analysis from Damien Duff, Liam Brady and Richie Sadlier, and commentary by George Hamilton and Ray Houghton.
