My sense is that you don't need to read this opinion. Because my strong guess is that we'll be reading about 17-year old A.S. at some additional point in the near future. When he's convicted of crimes and sentenced as an adult.
Sometimes you get the very, very strong feeling that certain people are nearly irrevocably down a path of long -- or even lifelong -- criminality. This is one of those cases.
Let's hope I'm wrong.
