Government ministers, newspaper columnists, ordinary people - they're all asking why the BBC doesn't say the Hamas gunmen are terrorists.

The answer goes right back to the BBC's founding principles.

Terrorism is a loaded word, which people use about an outfit they disapprove of morally. It's simply not the BBC's job to tell people who to support and who to condemn - who are the good guys and who are the bad guys.

We regularly point out that the British and other governments have condemned Hamas as a terrorist organization, but that's their business. We also run interviews with guests and quote contributors who describe Hamas as terrorists.

The key point is that we don't say it in our voice. Our business is to present our audiences with the facts, and let them make up their own minds.

As it happens, of course, many of the people who've attacked us for not using the word terrorist have seen our pictures, heard our audio or read our stories, and made up their minds on the basis of our reporting, so it's not as though we're hiding the truth in any way - far from it.

Any reasonable person would be appalled by the kind of thing we've seen. It's perfectly reasonable to call the incidents that have occurred "atrocities", because that's exactly what they are. No-one can possibly defend the murder of civilians.
