TEXT E
Policeman as a Writer
I decided to begin the term’s work with the short story since that form would be the easiest for the police of5cers, not only because most of their reading up to then had probably been in that genre, but also be-cause a study of the reaction of people to various situations was something they relied on in their daily work. For instance, they had to be able to predict how others would react to their directives and interventions be-fore deciding on their own form of action; they had to be able to take in the details of a situation quickly and correctly before intervening. No matter how factual and sparse police reports may seem to us, they must make use of a selection of vital detail, similar to which a writer of a short story has to make.
This was taught to me by one of my students, a captain, at the end of the term. I had begun the study of the short story by stressing the differences between a factual rep
A. dangerous but adventuresome
B. full of corruption
C. full of routine
