Fair enough
Let us know your address and we'll all come round at random intervals to see if you've left anything unlocked. You won't mind if we take anything because, after all, it will be your fault for leaving it unlocked in the first place. We'll all be blameless as we'll just be helping steer you in the right direction.
Just because I could punch anyone in the face as they walk past, doesn't make it right for me to do so. Even if they should have had their guard up just in case.
