Gudkov was serving as deputy chairman of the parliamentary Committee on Security during the 2002 Moscow theater hostage crisis , in which 40-50 Chechen Islamist separatists took over a theater holding 850 people . He blamed the failure of security forces to prevent the attack on a systematic destruction of state security institutions following the fall of the Soviet Union . In 2004 , he denied allegations that Russia was responsible for the death of former Chechen president Zelimkhan Yandarbiyev , stating that the KGB 's overseas assassination squad had long been disbanded
