They Have No Right to Confiscate Your Film
Sometimes agents acting for entities such as owners of industrial plants and shopping malls may ask you to hand over your film. Absent a court order, private parties have no right to confiscate your film. Taking your film directly or indirectly by threatening to use force or call a law enforcement agency can constitute criminal offenses such as theft and coercion. It can likewise constitute a civil tort such as conversion. Law enforcement officers may have the authority to seize film when making an arrest but otherwise must obtain a court order.
