I doubt if BP management spends time Photoshopping PR photos. It was done by the photographer/art director in whose lap this hot^H^H^Hwarmed-over potato should land. As usual, we have met the enemy and they is us.
What this suggests to me is that BP cuts corners in more areas than just safety.
They clearly hired on the cheap for their PR/photo freelancers, and tried to pull a fast one in terms of oversight. Hardly surprising, given the corporate culture today.
That said - BP is not a journalistic organization. They aren't bound to the ethics and expectations of a news outlet. However, given the public interest and scope of the situation, the onus is on them to be 200% upfront with the public...something they fell quite short of, clearly.
