I wouldn't call this well thought out letter a rant. Further he is putting his money where his mouth is: he is leaving so that his son can live in a safer situation.

Your experience about jury duty is important, but it was not in Chicago. I grew up there. I get what he's talking about.

Depending on the neighborhood, things can get very unsafe very quickly. No one talks about "what a disgrace" when they can hear gunfire three blocks away.
