An interesting article here on Slashdot:

Someone tried to search images on Google of Lynndie England, the US soldier that got in the news worldwide with the pictures taken of her with prisoners in the Abu Ghraib prison in Iraq. Nothing turned up. Enter a search for pictures of Abu Ghraib … no pictures with England either. Try the same on Altavista or Alltheweb … you do get to the shots you’d expect. So what is happening with the Google results… Google censorship or something else? It’s a scary thought that the (still) biggest search engine on the web should start to direct what we can and cannot see… Judging by this article, they’re certainly getting less popular.
