I can say that they leave a lot to be desired from a proper security procedures point of view. Retailers who don't properly train their employees are inviting the lawsuits that invariably follow a poorly handled shoplifting situation. Failure to train employees also invites other problems such as personal injury while attempting to detain suspected shoplifters, and even criminal prosecution of employees who assault or wrongly detain shoplift suspects. As to legal recourse, I recommend that you consult an attorney who is familiar with Pennsylvania law and get their opinion as to possible options. We have decorated our front yard for years for Halloween and Christmas.
People make special trips just to see our yard.
The problem we face is theft and vandalism. I have two camcorders that I leave on overnight and have floodlights connected to motion detectors. Even with these precautions, the only thing I can do is get a good picture of whoever is stealing or vandalizing. If the police don't know who they are, then there's really nothing they can do since they have much more pressing issues. However, just the other night, more of my decorations walked away.
