What happens when trick-or-treat candy (We're talking full-size candy bars here!) is left out for guests to take using the honor system?

The homeowner, who was away from the house at the time, left instructions:  "Help yourself but be considerate!" And then let the security cameras roll.

This may or may not come as a surprise to you, but dozens of kids abided. Everything went well until a parent, dressed as a not-so-sexy bunny, ruined it for everybody and scooped up all the remaining goods.
