No, the statement is not entirely accurate—it’s an oversimplification. Retail establishments (in the U.S., where this question most commonly arises) do have a qualified legal right to detain a suspected thief under the long-recognized “shopkeeper’s privilege” (or merchant’s statute in many states). However, they generally have no legal right to lock an exit (or otherwise obstruct a required means of egress) specifically to prevent that person from fleeing, primarily because of separate fire safety and building codes that mandate free, unobstructed emergency egress during business hours.
Most states recognize some version of this common-law doctrine (codified in statutes in places like Florida, Illinois, Michigan, New York, South Carolina, etc.). It allows a store owner, employee, or loss-prevention officer to:
- Temporarily detain a person on or near the premises if there are reasonable grounds / probable cause to believe shoplifting or theft occurred (e.g., they saw concealment and attempted exit without payment).
- Do so for a reasonable time and in a reasonable manner to investigate, recover merchandise, or summon police.
- Use reasonable (non-deadly) force if the person flees or resists violently.
This is a defense against claims of false imprisonment, false arrest, or unlawful detention—if the conditions are met. Courts emphasize that the detention must not be excessive (e.g., no prolonged holds, no forcing confessions, no off-premises transport without cause).

- If the method crosses into unreasonable force, excessive duration, or code violations, the store can face civil claims (false imprisonment) or even criminal liability.
- Exceptions like delayed-egress hardware exist in some retail settings for theft deterrence, but these are pre-approved systems—not ad-hoc “locking the door when you see a thief.”
Laws vary by state and locality. For a specific incident or store, consult local statutes, fire marshal rules, or an attorney. A blanket claim that stores have “no legal right” to do anything about a suspected thief is false, but the specific tactic of locking an exit is heavily restricted (and often outright prohibited) for good safety reasons.
