Were Russian images of voter fraud... fraudulent?

Since Russia's parliamentary elections earlier this week, dozens of videos have been circulating online claiming to show incidents of voter fraud. Our journalists contacted a man appearing in one video – he says he was prevented from participating in vote counting. However, BBC's Russian language service claims that through facial recognition technology, they have ascertained that actors participated in a video shown by the Electoral Commission. That video was supposed to show how fake scenes of voter fraud were being manufactured.
