Which of the following is true regarding searches conducted during an arrest?

Body cavity searches indeed require medical personnel due to the invasive nature of the procedure and the need for trained professionals to conduct it safely and appropriately. Such searches pose a significant risk to health and dignity, and therefore they must adhere to strict medical protocols. Law enforcement officers need to ensure that they comply with legal and ethical standards when conducting any type of search, especially those that could infringe upon an individual's rights and privacy.

The other options do not accurately reflect the limitations and requirements of searches conducted during arrests. While officers have the authority to conduct searches incidental to arrests, those searches must be reasonable and typically related to safety or the preservation of evidence. It is essential that officers act within the bounds of the law and established procedures, which is particularly clear in the context of body cavity searches that necessitate medical oversight.
