Officers arrest Ricardo Rojas inside his home on an outstanding warrant. While securing the premises, they hear movement in an upstairs bedroom and observe signs that another person may be hiding there. Relying on those specific facts, the officers conduct a limited sweep of areas where a person could be concealed. The sweep uncovers no additional individuals but yields incriminating evidence in plain view.
Rosa Ruiz faces an attacker who lunges with a knife. She draws a firearm and fires once, believing the attacker intends to inflict life-threatening injury. The shot stops the assault but causes permanent loss of function in the attacker's arm. Rosa's use of force is later evaluated under the standard that measures the harm she reasonably believed was imminent.

The belief must be both honestly held by the actor and supported by circumstances that would lead a reasonable person in the same position to reach the same conclusion.
Supporting sources

Supporting sources
In the protective-sweep context, officers must point to specific and articulable facts supporting their reasonable belief that the area harbors a dangerous individual.
Supporting sources
Yes. The focus remains on the harm the actor intended or reasonably believed would result, not on harm that unexpectedly occurs.
