This is not a joke. In all seriousness, the prosecutor's office for Moscow's Central Administrative District issued an order to the organizers of today's March in Support of the "May 6 Prisoners" stating the "inadmissibility of violating the law, specifically by placing images of public officials in improvised prison cells". There is no scan yet, but the quote is exact. Many thanks to the prosecutor's office. Now there will be a hundred times more "images of public officials placed in improvised prison cells" at every rally. The Streisand effect, after all. On the other hand, perhaps this is a subtle hint from some prosecutor's office employees expressing solidarity with the march participants: they would prefer to see p*ublic officials *in real cells, not improvised ones.
