We don't live in a perfect world and haven't for quite some time.  So use common sense because it goes a long way.  

Property has needed locks for longer than we've been alive now. So obviously moral decline has been around longer than we have.  Even in the 80s we still locked our doors.  

This isn't even the 2000's it's 2016, so let's not pretend like we don't know how  important it is to properly secure your valuables, or the valuables of others since he had an item on consignment.
