W: Welcome to our programme, Mr Smith.
M: Thank you.
W: Mr Smith, how long have you been a police officer?
M: I’ve been a police officer for thirty years.
W: Thirty years. And you’ve had different types of assignments on the police force, I guess.
M: Yeah, I’ve done everything from patrol to undercover work to detective work, and now I’m supervising investigations.
W: Mr Smith, I think most people would say that being a police officer is a very stressful job. Would you agree?
M: Yes, it’s definitely a stressful job. But it depends on your assignment.
W: So, what’s probably the most stressful job you can have?
M: I’d say patrol is the most stressful assignment.
W: That’s interesting! In what way?
M: Well, I guess the biggest part of the stress is the fear factor, the fear of the unknown.
W: What do you mean, Mr Smith?
M: Well, in patrol work, you don’t know from moment to moment who you are talking to or what their reaction is going to be to justify your presence. Let’s say, for example, a patrol officer stops someone for a traffic violation. It seems as though that would be a very low-stress situation.
W: Yes, it is a very low-stress situation.
M: But the truth is, there are more police officers injured during a routine stop.
W: Really?
M: Really! That’s why all police officers are taught from the very beginning to be aware of their surroundings: people back over policemen, people shoot policemen, people jump out at policemen — different kinds of things. So that’s probably the most stressful time.
W: I see. Let’s take a break and then we’ll move on to our next topic.
M: All right.
