Your story, which I understand will continue, shows great interest, @greenrun. You have initiated a plot that promises a good development. Kehinde presents himself as a complex character, not a simple one. Also this portion of the story that you offer us.
Prisons seem to be the same in much of the world (not to say all over the world). Overcrowding, dehumanized environment, mistreatment of guards, victimization, etc., characterize the generality of these prisons. There are also cases of people unjustly imprisoned or with inadequate sentences.
We still cannot know the truth of what Igala said. The truth is that the conscience of Kehinde - who seems to be someone inclined to solidarity and compassion - was moved by the testimony of the prisoner. We'll see how your interesting story unfolds. Greetings.
