I remember perfectly well when BBC was talking about what a massive threat Iraq was to Britain, and how Britain had to go to war with the US in Iraq. Not only was that a lie but it was also right wing or right in line with the US right wing agenda. Most people in Britain was well aware they were bullshitting, but there was not much anyone could do after Tony Blair and co had made up their minds.
People tend to trust the BBC but every now and then they make terrible misjudgements.
