Google has been asked by a US law enforcement agency to remove several videos exposing police brutality from the video sharing service YouTube, the company has revealed in its latest update to an online transparency report. Another request filed by a different agency required Google to remove videos allegedly defaming law enforcement officials. The two requests were among 92 submissions for content removal by various authorities in the US filed between January and June 2011. Both were rejected by Google along with 27 per cent of the submissions. The IT giant says the overall number of requests for content removal it receives from governmental agencies has risen, and so has the number of requests to disclose the private data of Google users.
