The most iconic character of The Wire is Omar Little, a robber of drug dealers who rips and runs. He makes enemies of the likes of Avon, Proposition Joe and Marlo, and eventually after a revenge spree in season 5, Omar is taken out by Kenard.
In a later scene, we see that a coroner notices Omar's name tag is wrong, so he changes Omar's name tag with another body. Why was Omar's name tag wrong? Why did the coroner switch the name tag of Omar. What does this scene mean.
