  COMING OF AGE IN THE EYES OF THE LAW: THE CONFLICT
             BETWEEN MIRANDA, J.D.B., AND PUBERTY

David  M. N. Garavito* and Mary Kate Koch**

                                   ABSTRACT

   Everyone  knows that going through puberty  is associated with a multitude of
changes: physical, mental, hormonal, etc. Fewer people know that when and how
fast one goes through puberty can also be associated with changes to one's legal
rights. The Supreme  Court  of the United States held, in the landmark case  of
J.D.B. v. North Carolina, that there were many commonsense   conclusions that
could  be drawn from  how a child's age would affect their interactions with law
enforcement.  In that case, the Court was  deciding whether  age  should affect
whether  a child was  considered in custody  of the police, granting them the
legal rights associated with  custodial interrogation (also known  as Miranda
rights). Surprisingly, however, despite the majority opinion discussing the objec-
tive nature of age, and commonsense  conclusions derived therefrom, the Court
did not fully incorporate age into the custody analysis. The Court held that the
age  only matters in a legal sense either if the officer(s) interacting with that per-
son knows  that the person is a child or if the age of the child would be objectively
apparent  to a reasonable officer. In other words, unless the officer(s) knows that
a suspect is a child, the influence of this objective fact about a person depends
solely on if that person looks like a child to a reasonable officer. Although
some  people find this shortcoming harmless, the Court has inadvertently opened
the door for discrimination, both intentional and unintentional. The vast amount
of biological and psychological  research on puberty  has found that when  one
starts puberty and how fast one goes  through puberty depends  on multiple fac-
tors, including socioeconomic status, race, and sex. Further, additional research
on  how  children are perceived by others shows that children of color are per-
ceived as more  mature and more  responsible for their actions. In this Article, we
provide a brief history of custody and custodial interrogation, including the case
of J.D.B., and we summarize  existing puberty research to emphasize the serious-
ness  of limiting the legal importance of age based  on subjective perceptions.
