Career
He was President of the regional Council in Piemonte from 1975 until 1980 and later deputy president of the Region till 1983. During the years he held office, the Italian Communist Party was divided on the issue of terrorism, with some members supporting and some members condemning far-left terrorism. Dino Sanlorenzo was strong defender of the democratic system, who opposed both far-left and far-right terrorism.
Within the Communist Party, he was one of the first to condemn far-left terrorism, taking a stance against the Marxist-Leninist groups.
He led the fight against terrorism groups in Piemonte, Prima Linea and Red Brigades. Even today, despite his advanced age, his is still active in conferences.
Dino Sanlorenzo never accepted the condescending expression "comrades who do wrong" (Italian: Compagni che sbagliano). His stance against terrorism induced the terrorist organizations, on July 24, 1979, to publish in the newspaper a death sentence against him from Prima Linea.
One terrorism group tried to carry out the death sentence, but a housemaid saw the armed group waiting for Sanlorenzo to return in his automobile and warned him.
The ambush failed.
