YouTuber Warned of Finnish Gunman

After 18 year-old Pekka-Eric Auvinen killed seven students and his principal at a Finnish high school Wednesday in an attack eerily similar to Columbine, media outlets reported that Auvinen had posted a YouTube video describing the shooting before he launched the attack, leading pundits to question why no one had noticed it in time to prevent the massacre.

But months before the fateful video was posted, one prolific YouTube user known as TheAmazingAtheist called for the police to investigate Auvinen and others who had been posting videos glorifying the Columbine shooters and Timothy McVeigh, saying they were showing warning signs of being more than simply infatuated or interested in violence.
