What measures can an officer use to suppress a riot?

The choice indicating that an officer can use only such measures as are necessary without using more force than necessary is grounded in the principles of law enforcement, particularly regarding the use of force. This principle emphasizes that while officers do have the authority to manage potentially dangerous situations like riots, their actions must be proportional and justifiable under the circumstances.

Applying this standard is crucial not only for the safety of those involved but also for maintaining public trust in law enforcement. Officers are trained to assess situations carefully and to use the minimum amount of force required to achieve their objectives effectively. This approach helps to control the situation while minimizing the risk of escalating violence or causing unnecessary harm.

This principle aligns with legal guidelines and departmental policies, which prioritize de-escalation techniques and the preservation of life wherever possible. Therefore, the correct answer reflects the importance of using force judiciously and responsibly in the face of civil unrest.
