The permission was given them. The terms of such a permission as you all know imply the certain time and especially place of the demo. I don't interest too much for National Bolsheviks rampages and the fits of that primitive swindel Kasparov, but as far as I know the place conditions were deliberately infringed to provoke the police. It's clear that all the leaders of the demo are greatly satisfied with the information resonance and the fotos of every truncheon make them piss of delight - I watched the channel Ren TV with interviews few minutes ago.
