Which of the following is a strategy to enhance security in a jail setting?

Improving staff training is a fundamental strategy for enhancing security in a jail setting. Well-trained staff members are better equipped to handle a variety of situations that may arise, such as conflict resolution, emergency management, and overall inmate supervision. This training includes understanding policies and procedures, recognizing signs of potential issues, and effectively communicating with inmates. When staff members are knowledgeable and confident in their roles, they can maintain order and provide a safer environment for both inmates and themselves.

In contrast, options like installing fewer cameras or reducing the number of staff present would likely lead to increased vulnerabilities and safety risks. Limiting inmate interactions can sometimes be necessary, but it doesn't address the root of security issues, which often depend on staff capability and preparedness. Therefore, focusing on staff training yields a more robust and proactive approach to ensuring jail security.
