Which of the following is considered contraband in a jail?

Cell phones are considered contraband in a jail setting due to their potential to facilitate communication between inmates and the outside world, which can undermine security and safety protocols. These devices can be used to coordinate illegal activities, intimidate witnesses, or orchestrate escapes. Therefore, their presence in a correctional facility poses a significant threat to the control and management of the institution.

In contrast, items such as combs, brushes, toiletries, and legal documents are typically allowed or regulated within jails as they do not inherently pose a security risk. They serve practical purposes for personal hygiene, legal processes, or general well-being and are deemed acceptable by correctional authorities under controlled conditions.
