People can be possessive, people can be happy people can sad, people can be healthy but then there are some who are just plain old obssessives. This sign was placed outside the property of a person who hated tresspassers, To scare them like hell he thought he should put up a sign so that nobody crosses the line. I bet nobody did cross the line here and even if they did I don't think anybody will ever know since the man sends the body parts ONE BY ONE to the police.
