Akkermans' photographs
He may well be a first-class news photographer. There are plenty out there. I have no wish to discredit the value of any illustrative content in these photographs. However "dressing the set" should be confined to studio photography - there's NO excuse at a crime scene, no matter what the nature of the items disturbed.
As for "knowing what to photograph", other than taking the obvious shots of airframe parts peppered with holes made from the ingress of sharp objects, many of which have appeared previously under many different bylines, you couldn't go wrong in this situation and his photographs resemble everything else shot at the scene. You'd have to be an air accident investigator to really know what to photograph other than the obvious.
And speaking of the obvious, the core information about this crime became available within about 12 hours of the event - well before those involved had time to "manage" the situation - and no objective person is likely to arrive at significantly different conclusions. The subsequent 5h!t-storm of obfuscation by every party with an interest (Russians, separatists, Ukranian government, USA) is already starting to obscure the picture.
