Which strategy is not necessary when maintaining security in a penal institution?

Ignoring minor violations is not a necessary strategy when maintaining security in a penal institution because overlooking such misconduct can lead to a breakdown in order and encourage further violations. In a controlled environment like a detention facility, even minor violations can escalate into more significant issues if not addressed promptly. Maintaining security involves proactive measures that deter and correct misconduct at all levels, ensuring a safe and orderly environment for both staff and inmates.

The other strategies—regular training sessions, continual observation, and random inspections—are crucial for effective security management. Regular training sessions ensure that staff are knowledgeable and prepared to handle various situations. Continual observation allows staff to be aware of their surroundings and identify potential risks before they escalate. Random inspections serve as a deterrent to prevent violations by creating uncertainty and reinforcing accountability among inmates and staff.
