RFE/RL today considers the question of why artists from the Voina collective seem to have received harsher treatment than their protesting associates in St Petersburg last week – three of them receiving charges, and one of them – Oleg Vorotnikov – beaten by police.  Vorotnikov was also beaten in a separate incident earlier last month, and his toddler son was involved on both occasions – evidence that the activities of the Voina art collective (such as its phallic drawbridge) are of particular irritation to the authorities.
