3.2 Merchant Detention, Probable Cause & Reasonable Custody
Key Takeaways
- Delaware's merchant-detention statute applies to a merchant, supervisor, agent, or employee who is at least eighteen and has probable cause for intentional concealment or shoplifting.
- Custody is for summoning law enforcement and must remain on the premises, in a reasonable manner, for a reasonable time.
- A complete, continuous observation process helps establish facts and prevents detention of the wrong person or unpaid-item mistakes.
- A loss-prevention policy may be more restrictive than the statute and must be followed.
What the merchant privilege does
Delaware's shoplifting law gives a merchant, supervisor, agent, or employee who is at least eighteen a limited power when there is probable cause to believe a person intentionally concealed merchandise or committed shoplifting. The authorized purpose is to take the person into custody and detain the person in a reasonable manner, on the premises, for a reasonable time while summoning a law-enforcement officer.
Every phrase matters. The rule is tied to retail merchandise and statutory shoplifting conduct. It does not create authority to investigate unrelated neighborhood crime, punish a customer, obtain a confession, or transport someone to another place. It also does not require a merchant to detain. Safety, employer policy, and the quality of the observations may favor continued observation and a police call instead.
Building probable cause from facts
Probable cause is more than a feeling and less than proof beyond a reasonable doubt. In a retail setting, a reliable decision often follows an observation path:
- Observe the person approach or select identifiable merchandise.
- Observe concealment, alteration, transfer, or other conduct relevant to the offense.
- Maintain continuity so the guard knows the item was not abandoned or paid for.
- Observe the person pass the relevant opportunity to pay or otherwise complete the conduct required by policy and law.
- Confirm the correct person and merchandise before contact.
The precise operational steps come from the merchant's approved loss-prevention policy. Some employers prohibit guards from making stops or require designated personnel and supervisor approval. The law establishes an outer boundary; it does not cancel a stricter policy.
A guard should be able to articulate the actual observations: “I saw the customer remove two tagged packages from shelf B, place both inside a backpack, maintain possession through checkout, purchase one unrelated item, and pass the final register without presenting the packages.” “The customer seemed nervous” is not an equivalent factual basis.
Reasonable place, manner, and time
| Limitation | Meaning in practice | Warning sign |
|---|---|---|
| On the premises | Keep custody at the merchant's property as the statute provides | Driving the person elsewhere |
| Reasonable manner | Use calm direction and no more restraint than lawfully necessary for safety | Threats, humiliation, interrogation, or needless force |
| Reasonable time | Summon police promptly and avoid avoidable delay | Holding someone for an employee's convenience or punishment |
| Lawful purpose | Preserve the situation for law enforcement | Forcing payment, a confession, or a waiver |
Reasonableness depends on the circumstances, including safety risks, cooperation, the arrival of police, and any urgent medical need. It is not a fixed number of minutes stated in the official study guide. The guard should record when observation began, when contact occurred, when police were called, significant events during custody, and when the person was released or transferred.
Safe contact and transfer
Before contact, notify the required supervisor and consider exits, companions, visible weapons, crowd conditions, and safe positioning. Identify the security role without impersonating police. State the reason for the contact factually and request cooperation. Do not search merely because detention occurred; search and consent are separate issues. If the person becomes violent, threatens a weapon, develops a medical emergency, or escapes, prioritize life safety, call 911, and follow force and emergency rules rather than treating merchandise recovery as the highest goal.
When police arrive, provide the observation sequence, identify video and witnesses, show the merchandise without altering evidence unnecessarily, and explain any gap in observation. Do not exaggerate to repair a weak case. If a critical element is missing, tell the supervisor and officer exactly that. Accurate uncertainty is more professional than false certainty.
Avoiding common failures
Common errors include stopping the companion rather than the observed subject, losing sight of the merchandise, confusing a personal item with store property, failing to see payment, acting on a vague radio message, and using the detention to demand information. Another employee's report can be relevant, but the guard must identify its source and comply with policy rather than presenting secondhand information as personal observation.
The core decision is not “Can I catch this person?” It is: Do the facts create probable cause for the covered conduct, does policy authorize my role, and can custody remain reasonable and safe while police are summoned? If any answer is uncertain, observation, documentation, supervision, and police assistance are the controlled alternatives.
