Thanks for pointing me to that David Simon quote. You are right: He is not going to spare us by sparing the kids. Gulp.
Thanks to the keen viewing of Slate editor June Thomas, I wanted to point out another visual metaphor, one whose significance I missed the first time around. (That's why this is a great show for repeat viewing!) The ring Michael took from Officer Walker has been stolen twice before. Walker took it from Omar, and Omar in turn took it off Marlo's finger during the heist that helped set the season in motion. As June points out, the ring ties these characters together by encircling them in despair and violence and greed. Maybe Simon will let one of the boys, at least, escape its clutches. As a mother and a citizen, I've got to hope so.
