After minutes of stillness punctuated by clicks and muttering, the camera pitches up and shows the close-shaved, youthful face of a man looking into the lens.
On Wednesday in the east German city of Halle, the man before the camera is preparing to commit a violent assault against a synagogue that will devolve into a random, blundering search for fresh targets.
Then the shooter readies an apparently home-made shotgun before driving the short distance to the synagogue, blasting hip-hop over a bluetooth speaker.
