The statute does not mention force. The statute says shopkeepers can attempt to recover stolen items. But it does not say how. However, the statute does say that shopkeeper's privilege is a defense against false arrest. And arrests nearly always involve using force. Such as holding someone down while waiting for the police to arrive. Still, it is recommended that merchants try reasoning with suspects to turn over the merchandise. If that does not work, merchants should then phone the police. Merchants should try to use as little force as possible - if any - to detain the suspect until the police arrive. The shopkeeper's privilege is not a defense to battery (NRS 200.481) charges. So if merchants cross the line by being too rough, they could face criminal charges as well as a civil lawsuit.
