In what circumstances can security guards perform searches?

Security guards can perform searches under specific circumstances defined by site policies or when there is probable cause. When authorized by site policies, such as during special events where guests may have agreed to certain terms upon entry, security personnel have the right to conduct searches to ensure safety and compliance with rules. Probable cause, which refers to having a reasonable belief based on facts that a search is necessary, further justifies the need for a search. This aligns with legal standards and professional conduct required within the security industry.

The other scenarios mentioned do not provide lawful or appropriate grounds for conducting searches. Performing searches simply based on personal discretion, contacting guests for permission on an arbitrary basis, or conducting them at will during patrols without any justification would violate protocols and could infringe on individuals' rights. Adhering to established policies and having valid reasons for searches helps ensure that security guards act within legal and ethical boundaries.
