'Bellingcat Report Doesn't Prove Anything' Expert Criticizes Allegations of Russian MH17 Manipulation

The research group Bellingcat has accused Russia of manipulating satellite images from the MH17 disaster. But German image forensics expert Jens Kriese has criticized the analysis. He says it is impossible to say with any certainty whether Moscow is lying.

Bellingcat analysis of Russian satellite data: "The conclusion is always based on the perspective of humans."

Bellingcat analysis of Russian satellite data: "The conclusion is always based on the perspective of humans."

Interview Conducted By

SPIEGEL ONLINE: Bellingcat made headlines around the world this week when it claimed on Sunday night it had proven that Russia's Defense Ministry conducted forensic manipulations. The allegation is focused on images of the shooting down of Malaysia Airlines Flt. MH17 in eastern Ukraine last spring.

Kriese: The term "forensic analysis" is not a protected one. From the perspective of forensics, the Bellingcat approach is not very robust. The core of what they are doing is based on so-called Error Level Analysis (ELA). The method is subjective and not based entirely on science. This is why there is not a single scientific paper that addresses it.

SPIEGEL ONLINE: What's the hitch?

Kriese: Forensic scientists use computer procedures that allow for the clearest possible conclusions: Has it been manipulated -- yes or no? Contrary to what Bellingcat claims, Error Level Analysis does not provide clear results. The conclusion is always based on the perspective of humans, on their interpretation.

SPIEGEL ONLINE: What does the method entail?

Kriese: It attempts to determine compression artifacts. Those are the small deviations created when a photo is saved in JPG format -- differences from the original. It is possible to depict them in color. But: The final decision on whether a manipulation has occured or not is then still a personal decision made by the viewer. One has to decide whether variations should be attributed to manipulations or are they normal and could be attributed to clouds, for example?

SPIEGEL ONLINE: Do you consider the Russian satellite images to have been manipulation?

Kriese: That's not the right question. We are not talking about satellite images here. We only know the version published by Moscow. That is a satellite image that has been prepared for use in a presentation.

SPIEGEL ONLINE: Bellingcat has come to the conclusion that they were edited using Photoshop.

Kriese: That's an erroneous interpretation. They claim that the metadata shows that the images were processed using Photoshop. Based on that they are concluding it was the clouds that were likely added in order to conceal something. The truth is that the indication of Photoshop in the metadata doesn't prove anything. Of course the Russians had to use some sort of program in order to process the satellite image for the presentation. They added frames and text blocks in order to explain it to the public. The artifacts which have been identified could be a product of that -- or also a product of saving multiple times in JPG format.

SPIEGEL ONLINE: Bellingcat says its findings are based on the use of the analysis tool FotoForensic.com, a website.

Kriese: And its founder Neal Krawetz also distanced himself from Bellingcat's conclusions on Twitter. He described it as a good example of "how to not do image analysis." What Bellingcat is doing is nothing more than reading tea leaves. Error Level Analysis is a method used by hobbyists.

SPIEGEL ONLINE: How could one really test whether the satellite images have in fact actually been manipulated?

Kriese: That is very difficult. Ideally it would require the original documents, the satellite images themselves or perhaps even the raw data. The Russians have them.

SPIEGEL ONLINE: Can't raw data also be manipulated?

Kriese: That is laborious. Other methods are more effective. There's an entire discipline exploring how image manipulation can be concealed. It is called anti-forensics. It allows photos to be sharpened after they are taken or to be edited with blur filters. Ninety percent of the time, ambitious bloggers like Bellingcat get nowhere.

SPIEGEL ONLINE: So how is it even possible to uncover falsifications?

Kriese: Most are created under time pressure, which leads to small mistakes. But no one would be reckless enough to use Photoshop of all things and then not clean up the metadata. There are very different variants, and I think the intelligence services know a few of them.

SPIEGEL ONLINE: Satellite images are often used as proof of events in the Ukraine crisis, even by NATO. Are they even meaningful?

Kriese: It is easy to claim to amateurs that one can see this or that. But just think about the US images of the alleged poison gas facilities in the Middle East. There's a similar point at Bellingcat: In one of the photos, a growing spot can be seen. It's allegedly an oil puddle next to a vehicle. But does one consider that to be plausible? I think it depends on whether a person wants to believe it or not.

SPIEGEL ONLINE: What's your personal conclusion about the satellite images?

Kriese: The first thing to die in war is the truth. Each side likes to throw random smoke bombs. There is no way of knowing if the images show what Moscow is claiming. What one can say, however, is that this "analysis" has achieved nothing besides raising awareness of Bellingcat.

1. Believe nothing you have not experienced yourself
Hitler lied, so did Stalin, Roosevelt, Benes, Sikorski and Churchill, little would appear to have changed in the top levels of politics since the last century. Can we genuinely say whether Putin, Obama, Merkel or Erdogan currently tell us the truth. The answer is, we cannot be in any way sure! Too much was and is being manipulated. For those of us who lived through WW2, some manipulations of the presentations of historical events have become more than obvious. When three generations of Americans and Europeans have grown up to believe these partly false and often extraordinary stories of the past, who is in a position to tell us what is the truth of current affairs? Certainly a number of so-called experts, who are often called upon to give comments in TV programs, have less knowledge than the many ordinary citizens watching. With the enormous possibilities given by modern computers, to alter pictures and other data, few are in a position to know what is really going on in the world around them.

2. Who is telling the truth?
The only sure analysis of which country is telling the truth is to assume they are all lying. None of our governments is trustworthy these days. It is a sad indictment of modern civilization that we are led by the nose by self serving political parties most concerned with their own power and little inclination to find peaceful resolutions to conflict.

3. Bellingcat is NOT a reliable source
It is not the first time they manipulated the data in an erroneous way in order to ''prove'' that Russia ''lies''. It seems to be their ''job'' - maybe they were hired to create those diversions so we are distracted from the reality on the ground. What about the high resolution images from US spy satellites which were over the Ukraine when the MH17 tragedy happened? When those images will be presented to the public?

4. Pro-Kremlin disinformation
So now, even iwhen the Russian manufacturer of BUK anti-aircraft battery admits itself that Malaysian Boeing-777 was shot down by its missile Der Spiegel finds a biologist (sic) who claims that it cannot be proven, just like Russian creating phoney photographic evidence. Aren't you people ashamed of yourselves?

5. German Experts?
Given the subservience of Germany, i.e. Merkel, Der Spiegal, to the Americans, nothing coming from Germany about Ukraine can be trusted. Merkel knows that NAZIs are alive and thriving in Kiev and that Ukraine shot down M17 but, under American orders, will not say so.
