"Indagine su un cittadino al di sopra di ogni sospetto" is an Italian political film. It is a fierce attack on the fascist style of politics and the corrupt and dirty activities within the police station. It is extremely pungent in terms of expression. Without losing the calmness, the plot buckles one after another, with ups and downs
.
The artistic technique of director Elio Petri is rigorous and powerful. The performance of the protagonist Gianni Santuccio is also very good. However, in the second half of the film, too much expressionism is used to express the character's abnormal psychology. The police officer is like a character in Fyodor Mikhailovich Dostoevsky's novel. His behavior and spirit are abnormal, which weakens the original political meaning.
