A lot of scrutiny has been paid to the backpacks that the suspects carried and those that were found at the bombing scenes. Almost all of the backpack examinations are part of the “Dzhokhar Was Framed” conspiracy theories, but I think they deserve analyses of their own. Here are some of the backpack examinations that gathered steam.
1) The picture of Dzhokhar Tsarnaev fleeing the bombing scene has been doctored to remove his backpack
This video claims to show that the photograph that David Greene took on his cell phone was doctored to photoshop out the backpack Dzhokhar was carrying. I do not know enough about photoshopping to debunk this but others in the comments have pointed out that digital images often have an effect that is called “ghosting” that can be the cause for the pixelation that 2Minstral claims to see. Additionally, there is a debunker video for those who know and understand digital photography. All conspiracy theory has some element of harm in it, be it twisting or obfuscating the truth to actively destroying the lives of innocent people. This theory has led to a sort of online pillory of David Greene, the man who took the picture, as some people accuse him of altering his own photo. Some of the theories indicate that the FBI was responsible for photoshopping this picture. But Greene has still caught blowback from people who accuse him of wrongdoing.
This theory also feeds into the sixth backpack theory I discuss, as there is belief that there is a conspiracy to hide the fact that Dzhokhar left the bombing scene with the same backpack he was seen wearing in the surveillance video.
