Final answer:
The minimum age at which a juvenile is generally not detained in secure custody in a police facility is usually 12 years old, aligning with juvenile justice policies focused on alternative care.
Step-by-step explanation:
In accordance with prevalent juvenile justice policies, the general threshold for not detaining a juvenile in secure custody within a police facility is commonly set at 12 years old (Option b). This policy is formulated to safeguard very young children from the potential risks associated with secure detention unless deemed absolutely essential. The intention is to prioritize alternatives to incarceration for juveniles, ensuring their well-being and development.
Instead of placing juveniles in secure detention, authorities explore alternative measures such as releasing them into the care of a parent or guardian. Additionally, non-secure facilities are considered, emphasizing the care and rehabilitation of younger juveniles. By implementing these policies, the juvenile justice system aims to balance the need for public safety with a commitment to the welfare and rehabilitation of juvenile offenders, particularly those at a tender age.
