The prosecution pulled a couple of astonishing 180°s in the Dzhokhar Tsarnaev trial Thursday. The fancy footwork actually had the government denying evidence it once claimed to have possessed. In fact, in one instance, the prosecution managed to pull a full 360°.

It started when one witness, FBI Supervisory Agent Michael Knapp—who works with the Terrorist Explosive Device Analytical Center (TEDAC) in Quantico, Virginia—testified that the bombs allegedly made by Tamerlan and Dzhokhar Tsarnaev were “not that sophisticated.” He also stated that investigators found explosives residue in the Tsarnaev brothers’ Norfolk Street, Cambridge, apartment and in their vehicles.

However, both these assertions directly contradict what the public has been led to believe since the April 2013
