The Google-owned YouTube has removed videos posted by Elliot Rodger, the gunman who killed six students in California last week.

The site said the clips violated its terms of service regarding videos that threatened violence.

A spokeswoman said the videos were "against YouTube's guidelines" and were removed when flagged.

But experts warned that removing them might accelerate their spread around the internet.

Before killing three of his housemates, and then going on to shoot at random from his BMW, Rodger posted videos on the video-sharing site describing his plans.

In one, filmed in his car, he said: "Tomorrow is the day of retribution. The day in which I will have my revenge against humanity, against all of you."

Technology solution?

The incident has led some to question whether technology can be used to flag disturbing content online as a way of stopping similar events.

Google, like other companies that offer media-sharing services, has developed sophisticated methods to detect and deal with videos that contain copyrighted content, such as music.•••

–グーグルがオーナーのYouTube.　
　先週、カリフォルニア州で６人の生徒を殺したガンマンのビデオを削除した。
　ガイドラインに抵触しているという理由だ。
　犯行をにおわせる発言をしているビデオもあった。
　こうした検閲的な行為に警鐘を鳴らす専門家、というのもいるが、そこは人間の判断しかないだろう。
