Last Sunday, on the HBO late night talk show Last Week Tonight, comedian John Oliver took on our criminal justice system. He began by showing a clip from Sesame Street, where Muppets were explaining incarceration to children. Like many kids, I grew up watching Sesame Street - most of my memories just involve puppets singing songs about the importance of sharing, counting to 10 in faux accents, or, in the case of Cookie Monster, hunting for cookies. For me, this was a reminder of how much things have changed, even in just my lifetime. Today, nearly 2 million children are growing up with a parent in prison or jail and nearly 1 in every 100 Americans is currently behind bars.
