YouTube has removed a number of videos glorifying the Columbine High School killers, after a BBC investigation.
Videos found on the site praised Eric Harris and Dylan Klebold – also known as “Reb” and “Vodka” – for carrying out the shooting, in which 13 people died.
The killings near Denver, Colorado nine years ago, were romanticised in some of the videos which have now been removed.
A YouTube spokesman said the volume of content submitted meant not all can be checked before reaching the site. (BBC News)
