Your assumption of the powers of loss prevention personnel is incorrect. Loss prevention personnel can "detain" a shoplifter while awaiting law enforcement only after they have "personally viewed" the offense taking place. These privledges are sometimes abused but are rarely charged. The same law allowing private citizens the ability to "detain" while awaiting the arrival of L.E. is what loss prevention use. I know this as I am a former Loss Prevention Detective. This was explained to us in the first few days on the job. No special powers of arrest or sworn ceremony are offered to most loss prevention or store security persons.....most , not all. Some companies hire private police which is a different thing altogether.
