If this is from a written text you were given as part of a language course, you need to ask serious questions of the course organisers. "Chief of Police' is not a BrE term as far as I know. Who needs to know sheep shearing vocabulary? I expect there are many parts of the world in which this story would make some sort of sense or even be rather amusing. The UK is not one of them. Unfortunately the words thug and hoodlum might be, but not in this context."Once upon a time a man whose sheep was sheared too much got upset, he could not believe those animals were all sheared to the bone. The week after heard from the radio that the same man who hiddenly sheared all those sheep was going to become the chief of the police. A beautiful morning the press came to his house, asking him his take about the new police's chief: " Mr. Mister, how is it going with your sheep, where is all the fur to make the wool you need and by the way Do you know that the man you claim to be the hoodlum is going to be our police's chief?" he promptly replied :" He is nothing but a thug, so what?"
