In which case can an officer present at a scene be held liable for not acting against excessive force?

An officer can be held liable for not acting against excessive force when it is established that they had a duty to intervene and failed to do so. This is often articulated in legal cases where the courts recognize the obligation of officers to protect individuals from harm, including harm inflicted by other officers.

In the context of the case referenced, it has been established that officers who are present and witness excessive force being used by their colleagues are expected to intervene to stop it. Failure to act in such situations can lead to civil liability. This understanding emphasizes the principle that police officers not only have a duty to enforce the law but also to prevent unlawful actions, which includes intervening against the excessive use of force when it is reasonable for them to do so.

The cited case demonstrates this concept in action, outlining the consequences for officers who do not uphold their responsibilities in situations of excessive use of force. Expanding upon this, courts are increasingly supportive of holding officers accountable for their inaction in such contexts, reinforcing the importance of protecting citizens' rights and maintaining accountability within the police force.
