So it seems that google is not showing the images about the Berlusconi’s aggression:
With Bing you can find the images, with Google no. Check here.
The post from google italia to answer the user questions is about a possible delay within the scan of the pages and the results from the engine.
Which is reasonable, but this is not the case.
Yesterday it was possible to find them. On Google Images. Not today.
The question is why?
Update: it seems now you can find them, so the google spider for images is a bit lagging behind.
