"Under the law, 16- and 17-year-olds are minors. They can't sign contracts or leases, buy alcohol, join the military, serve on a jury, or engage in a host of other activities that only legal adults are qualified to engage in because we as a society have judged that they have not yet developed the experience and judgment to make such decisions. They aren't even treated as adults when they commit crimes, except under exceptional circumstances, for the very same reason."
