Cavity searches must be based on what?

Cavity searches must be based on probable cause to ensure that the rights of individuals are protected while maintaining the safety and security of the facility. Probable cause refers to a reasonable belief, based on facts, that an individual may be concealing contraband or other dangerous items within their body. This standard is in place to prevent arbitrary or discriminatory practices during searches, which could violate a person's rights under the Fourth Amendment, protecting against unreasonable searches and seizures.

Conducting cavity searches without probable cause could lead to legal challenges against the facility or the officers involved, as it may be viewed as an invasion of privacy and a misuse of authority. This requirement helps maintain the integrity of law enforcement practices and ensures that searches are not performed lightly or without justification.

Other options, such as random suspicion, convenience, or mere officer discretion, do not provide the necessary legal foundation to justify the invasive nature of cavity searches and could be construed as violating an individual's rights.
