> Could be. But by whom? To what effect? The general public. I speculate that publicity was one of the main objectives behind this operation to draw attention to his political grievances and maybe demands. Perhaps we should focus more on the issue of bragging rights. The perpetrator probably thinks he's some kind of a hero having conducted this operation and it was some kind of a heroic feat sticking up to Putin when he in fact is more of a lousy vandal destroying some poor guy's store window than an epic warrior conquering foreign lands and subduing evil emperors. The more people realize this and esp. people who are prone to commit these acts, the more innocent people would be spared the damage incurred by those reckless attacks.
