I think the real target of al-Qaeda is Saudi Arabia by the way. They hate us and we're a vehicle to get at Saudi Arabia. I think Osama bin Laden really wants to topple that regime and have his people move in, but that's a whole other story.
It's totally mistaken to suppose that an armed escort is going to give a journalist any protection - on the contrary, journalists who turn up surrounded by armed personnel are just turning themselves into targets and in even worse danger.
