What a surprise, really. PiS have used a fake profile to cause trouble, and now they'll use their goons to harass and threaten Kijowski. It's all entirely predictable - just like in Russia, opposition is dealt with through smears, slander and the security forces.
Any proof? You seem to believe only what you wnat to believe, If Petru says something the only thing an honest person can say is: "Petru said such and such", not that what he said was gospel.
The proof is in the fact that it wasn't posted from Kijowski's profile, perhaps?
To those who never smelt tear gas, felt the sting of a ZOMO baton, were bowled over by water cannon or hauled down tot eh polcie station for questioning, the KOD nonsense will provide a welcome resptie and diversion from the boring Internet and same old pub.
I have a terrible feeling that we will experience exactly that sooner rather than later. The PiS nationalist goons are already planning to attack KOD on Saturday in Warsaw.
