College professors are not necessarily the “role models”; their jobs are knowledge teaching, method introducing and problem solving for the students. If someone is able to do well in these three aspects, then they can be a professor.
Since most of the college students are over 18 years old, I believe they have already developed their own principle and value of life. They also have mature sense of right and wrong. I think college students are not going to follow someone blindly. Therefore I think if the professor has another special profession, there will not be significant impact on students themselves.
However it is interesting to see a journalism professor also works as a prostitute. Gerald Hannon seems feeling nothing wrong with it. He even enjoyed sharing his experience with the audiences because he thought he knew better than anyone else on this certain case. I do not mind if my professor talked about this topic in class because I agree that people like Hannon will hold a better view on people who are similar to himself. I am interested in the mental world of the people mentioned in his article. He raised several examples like the boy Jim, the married man; I felt that they all have their unique thought. In addition, although Hannon involves in an activity which is against the law after class, it won’t affect his profession as a professor. (If he did not make an appeal to all of his students that everyone should try this). I mean every professor have done something illegal, like over speeding or drunk driving etc.
Nevertheless I will not ask my professor about this issue. That is his “part-time job” in his private life. I think it is rude to ask someone’s private life if he/she does not want to refer to class of their own accord. After all, being a prostitute can be relevant to journalism class (you can regard it as something news-worthy) or irrelevant. It is not something that we must care about.
At last, although Hannon knows those people well, I do not think he can use them as resources. Their relationship is a controversial one and they are kind of too close, physically. Moreover, Hannon might reveal something that those people do not want public to know, his behavior of mentioning those people in his article can be harmful to his “clients”. Hannon may be fine with telling people he works as a prostitute, but this might put those people who called him in a trouble situation.
