"The Trial" by Walter Mosley, in Freedom: Stories Celebrating the Universal Declaration of Human Rights, by Amnesty International. 2011.
Interesting idea. Each story in this book is tied to one of the articles in the Universal Declaration of Human Rights. (Some articles inspired several stories.) I can't tell you how good the whole book is because I just got it and jumped ahead to one of my favorite authors.
Walter Mosley's piece is inspired by Article 7: Equality Before The Law, which is not something his characters feel they have been getting much of. They are African-Americans, residents in a housing complex where drug dealers can get an easy pass from the bribe-taking cops, but more "serious" crimes are punished without much consideration of the issues that caused them.
In this case a drug dealer has been murdered and various community members - his lover, his sometime assistant, the oldest resident, a successful businessman, etc. - have gathered to decide the fate of the confessed murderer.
As the story goes on it goes through fascinating shifts - Was Wilfred the killer justified? Does this group of neighbors have the right to rule on him? Do the courts?
Mosley writes with the easy conversational style of a great mystery writer, but he is discussing deep, deep issues here.
