Myth: Security Guards Can Arrest Anyone They Want

The myth

Movies and some overzealous training programs create the impression that a uniformed security guard has police-like authority to detain, search, or forcibly remove anyone on a property. This leads to two problems: property owners sometimes expect guards to handle situations that legally require police, and occasionally a guard oversteps, creating liability for everyone involved.

The reality

In California, security guards generally have the same citizen's arrest authority as any member of the public — they can detain someone in narrow circumstances (such as witnessing a crime), but they don't have the broader powers police have, like conducting searches without consent or making arrests based on reasonable suspicion alone. Licensed guard training in California, overseen by the Bureau of Security and Investigative Services (BSIS), emphasizes observation, documentation, and verbal de-escalation as the default approach specifically because physical intervention and improvised arrests carry legal risk for the guard, the company, and the property.

This isn't a limitation to be worked around — it's the reason a well-run security program reduces incidents without turning into confrontations. A guard who calmly asks someone to leave, documents the interaction, and calls police if the person refuses is doing the job correctly, even though it looks less dramatic than a forcible removal.

What to do instead

If a situation on your property needs an arrest, a search, or any use of authority beyond what a private citizen has, call 911. Your security provider's role is to observe, document, de-escalate, and support responding officers — ask any prospective vendor how they train for exactly this line, and be wary of any company that promises more 'authority' than the law actually gives a private guard.
