What is a basic guideline regarding the use of firearms during police encounters?

The guideline stating that firearms should be used only when absolutely necessary is grounded in the principles of proportionality and necessity in law enforcement. This principle emphasizes that police officers are trained to use lethal force, including firearms, only when there is an imminent threat to life or serious bodily harm, either to themselves or others. This approach aligns with the constraints of use of force models that prioritize de-escalation and the sanctity of life.

In high-stress situations, officers must assess the level of threat and choose an appropriate response that minimizes harm while effectively protecting themselves and the public. The focus on necessity discourages the arbitrary or excessive use of force, thereby fostering accountability and maintaining public trust in law enforcement practices.
