Is it right or wrong for Jimmy to tell a plainclothes officer to arrest Bob?

This is a tricky question for the reader to answer, for it can go either way. The reader could argue that it is wrong for Jimmy to betray his old pal in this manner, especially since they were the best of friends, almost brothers to each other. The fact that the two remember to keep an appointment made almost twenty years ago shows that they hold their friendship in high regard. Bob speaks highly of Jimmy to the policeman (who is, in fact, Jimmy himself). He says this of his friend: “Jimmy always was the truest, staunchest old chap in the world.” Bob has traveled far, over a thousand miles, to see Jimmy. Also, the fact that Jimmy does not have the guts to arrest his friend by himself shows that he feels something for his friend. Had his feelings been strong enough, perhaps he wouldn’t have been able to send a plainclothes policeman to arrest his friend. We can put ourselves in Jimmy’s shoes and try to think of Bob as a brother who has walked back into our lives after such a long time, only for us to realize that he is a sought-after criminal. What would we do? Would we turn over our friend to the cops?
The reader could also analyze Jimmy’s behavior in terms of general morals and values. Jimmy owes it to his profession to do right, to observe the law even if at the expense of his own friend. Bob has chosen the wrong path of life and must not expect any favors from his friend. By turning him in, Jimmy has saved a multitude of people who have suffered from Bob’s criminal activities.
