I think you're missing Mo Amin off your list (there is a page on Wiki but I think it's far from doing him justice).
At the end of the day without people like this you'd have the majority of the population sitting in blissful ignorance, which may be the way some of you want it (if this is the case then might I suggest you stick to reading the Sun), but I think that it is important that someone has the courage to put themselves in danger to get the story told (without which I suspect there would be a lot more people dying of starvation as well as torture and murder victims).
