Absolutely correct. Loss Prevention can follow them to get a description or track their movements on cameras throughout the store but they are prohibited from physical contact. More so they can do nothing to a Customer they see put merchandise in their pockets until that Customer tries exiting the store. I think the only think that makes physical contact permissible is if the Customer attempts to get physical with the Loss Prevention personnel then it's acceptable as a means to detain until police show up. Might be wrong but I think holds are allowed.
