The Company Reuters Keeps

Omar Abed Qusini, via web conferenceOne quick question: Is it appropriate for photographers who are members of a group called Artists Against the War (or translated via google) to be sent into war zones to document the events as they transpire? And, even if Mr. Qusini were not a member of this group, would his objectivity still be called into question by his association with them? I mean, can we expect someone of that nature to be non-partial in their coverage of events? Can we trust that they'd be able to tell us the truth about something they're wholly opposed to? I'd certainly like to hear what you think, whether you're an interested observer, or are a wire photographer. Do memberships in groups like this affect the coverage you would expect from current events?
