 Hillar Aarelaid, manager of Estonia's Computer Emergency Response Team "expressed skepticism that the attacks were from the Russian government, noting that Estonians were also divided on whether it was right to remove the statue".Clarke and Knake report that upon the Estonian authorities informing Russian officials they had traced systems controlling the attack to Russia, there was some indication in response that incensed patriotic Russians might have acted on their own.Regardless of conjectures over official involvement, the decision of Russian authorities not to pursue individuals responsible—a treaty obligation—together with expert opinion that Russian security services could readily track down the culprits should they so desire, leads Russia observers to conclude the attacks served Russian interests.
