Quote context

- The beast must be destroyed. He has injured one man badly and he might kill others.

- My duties are to the welfare of my people, not this crazy scientific experiment. Andiamo.

- Signore commissario, you can't do that! Signore commissario! Signore, please wait!

- That is my position. The safety of the people in this district is my affair. My primary affair as long as I'm commissario. Maybe you can have me replaced. That, of course, is your privilege. Until then, I will function as commissario.

- You are an efficient man, signore. A man of sincerity. There will be no thought of replacing you.

- Then I must say that, at daybreak, I intend to use every means at my disposal to destroy that creature before he kills someone.

- I know that, sir, but...

- Before the commissario has him destroyed?

- Not for me. Signor Contino?

- How do you propose to do this?
