Which of the following is a benefit of using body cameras in law enforcement?

Using body cameras in law enforcement significantly enhances accountability and transparency, which is why this answer is correct. Body cameras capture interactions between police officers and the public in real time, documenting what occurs during encounters. This video evidence serves multiple purposes: it provides a truthful account of incidents, it can be used to review officer conduct, and it helps build trust within communities by showing that law enforcement is committed to accountability.

The implementation of body cameras contributes to an environment where both officers and civilians are more likely to behave appropriately, knowing that their actions are being recorded. This transparency can lead to more thorough investigations into incidents and can also deter misconduct on both sides.

The other options don't accurately reflect the utility of body cameras. While they don't eliminate the need for written reports, they are not limited to only recording audio as they capture both video and audio. Moreover, body cameras are not specifically designed for surveillance of public gatherings; their primary purpose is to document police interactions directly related to law enforcement activities.
