Which of the following is considered a lawful use of force?

The use of force to prevent a crime is considered lawful because it aligns with the legal principles that allow law enforcement officers to act in a protective capacity. When a crime is in progress or imminent, officers are permitted to intervene to safeguard individuals or property from harm. This justification is grounded in the need to maintain public safety and order. Police officers are trained to assess situations quickly and apply necessary force to prevent further criminal activity or to protect themselves and others from imminent danger.

In contrast, other options describe scenarios where force lacks justification. Intimidation does not constitute a lawful justification for force, as it aims to instill fear rather than prevent harm. Additionally, using force without justification is illegal and can lead to civil or criminal consequences for the officer involved. Finally, the use of force after a suspect has fled might also be problematic, as it typically does not meet the immediate threat standard required to justify force; officers are generally expected to de-escalate situations where there is no immediate danger following a suspect's flight.
