users have been trying to guess whether the appearance of Bonnie and Clyde at such a symbolic event for the Kremlin was a shockingly inappropriate mistake or a silent protest, an act of defiance and mockery by a dissenter from President Vladimir Putin’s regime.

It might have been a mistake, a simple miskey of a file number. But if I had to put money on it, I’d go with the “defiance and mockery” theory.
