Under what condition does a park warden have the authority to search incident to arrest?

A park warden has the authority to search incident to an arrest primarily when it is necessary for officer safety or to secure evidence. This principle is rooted in the idea that immediate searches can help protect the officer from potential harm and prevent the destruction of evidence associated with the arrest.

This authority is aligned with broader law enforcement practices where searches made at the time of arrest are justified to ensure a safe environment for the officer and the public, as well as to maintain the integrity of the investigation. It is critical for park wardens to act within their legal scope and the requirements of safety and relevant context determine when such searches are appropriate.

The other options suggest conditions that are either too broad or too restrictive. For instance, the notion of always having the authority regardless of circumstances does not take into account the need for justification based on safety or evidence.

Similarly, requiring authorization by a magistrate could delay necessary action in a situation where immediate safety or preservation of evidence is at stake, and assuming that a search is appropriate in all instances of suspected crime ignores the legal standards that necessitate demonstrating specific grounds for a search.
