28-A M.R.S.A. defines a minor as someone who is under the age of:

The definition of a minor under 28-A M.R.S.A. specifically sets the age at which an individual is considered legally an adult at 21 years old. This legal framework is particularly relevant in contexts such as alcohol consumption and certain other adult responsibilities and rights. Recognizing someone as a minor if they are under 21 ensures that legal distinctions are maintained regarding who has the capacity to engage in activities restricted to adults.

This definition is critical in a policing context, as officers need to understand the legal implications of how they interact with individuals of different ages, especially regarding enforcement of laws related to substance use, curfews, and other age-dependent regulations. By defining the threshold at 21, the statute helps distinguish between the rights and responsibilities of minors versus adults, thereby guiding law enforcement in their duties and community interactions.
