what is the conclusion in after twenty years?

The two men, Silky Bob and Jimmy Wells, grew up together
and were very close.  When they each decided to go different ways, Bob to find his
fortune in the West and Jimmy to settle in New York, they made a promise to each other
that they would meet 20 years later at the same restaurant. Silky Bob was there waiting
for Jimmy.  The restaurant had changed and was now a cigar store.  A police officer
stops and Silky Bob tells him the story.  Later, another man approaches, and Bob assumes
it is Jimmy.  Finally he realizes that the man couldn't be Jimmy because Jimmy's nose
was a Roman nose and this man had a pug nose.  The ironic thing is that the police
officer was Jimmy Wells.  He couldn't arrest his good friend, but he did recognize him
as a wanted man.  So, he arranged for a plainclothes officer to meet him and arrest
him.
