I'm wondering why they referred to him as a "17-year-old man"? 17 years old is hardly adulthood. It's getting close, but I don't think most 17-year-olds are really at an adult level of maturity. On top of that it's simply not legal adulthood. I think "17-year-old boy" would be more accurate and not seem an attempt to stretch the truth to be able to try him as an adult.
