Which of the following is a legal power typically granted to security guards?

Security guards typically have the legal authority to detain individuals temporarily when they suspect that a person has committed an offense, especially on the property they are assigned to protect. This power is often referred to as the right of "citizen’s arrest," which allows security personnel to hold a suspect until law enforcement arrives. Detaining someone is meant to ensure the safety and security of the premises and can be crucial in preventing further illegal activity.

In many jurisdictions, this authority is limited and comes with specific guidelines that security guards must follow to avoid legal issues. For example, they may need to have reasonable grounds for the detention and are generally expected to manage the situation with minimal force and in a professional manner.

The other options listed typically do not fall within the legal scope of powers granted to security guards. Making arrests is generally a power reserved for law enforcement officers. Conducting background checks usually requires specific authorization or a process that security guards are not equipped to perform. Issuing tickets tends to fall under municipal authority or law enforcement jurisdiction, not the remit of security personnel.
