In April 2008 , a government decree stated that classified documents can not be kept secret for more than 30 years , giving accessibility to documents that had been made secret more than 30 years before . The end of the State secrecy " does not automatically lead to the revocation or disclosure of classified documents " The Italian mafia 's association Cosa Nostra tried to influence the political and judiciary events also by resorting to violence , through the usage of explosives in order to spread terror .
