According to the Penal Code, what limits the justification of deadly force usage?

The correct answer recognizes that the justification for using deadly force is heavily dependent on the immediate threat posed by a suspect. The legal standard generally requires that a person must perceive an imminent threat to their safety or the safety of others to justify the use of lethal force. If the suspect poses no immediate danger, then the justification for using deadly force is significantly weakened, as the use of such force is not considered necessary or reasonable.

In this context, the presence of witnesses does not inherently limit the justification for using deadly force, nor does it guarantee that use is justified. The condition of being in the presence of witnesses is irrelevant to the assessment of immediate danger.

Similarly, limiting the use of deadly force strictly to situations occurring during an arrest ignores other credible scenarios where immediate threats may arise outside of that context. Additionally, while feeling threatened can influence a person's decision to use force, it must be paired with the objective measure of whether there is an actual immediate danger. Just relying on one’s feelings without the presence of a legitimate threat could lead to unjustifiable uses of force. Thus, the absence of immediate danger is a key factor in evaluating the justification for deadly force usage.
