"This Aggression Will Not Stand, uh, Man" - the Dude

For 9 years we have lived on this hill in almost complete seclusion. Being one of two houses on a steep hill that dead-ends into our driveway usually keeps out the door-to-door sales people and even the trick-or-treaters for that matter. We have NEVER, EVER had a regular trick-or-treater. Safe from the outside world, or so it would seem. I went out to feed our dogs last night and found this in my yard. VANDALISM!!! FULL ON GARBAGE DUMPING VANDALISM!!! This happened not once but twice! I cleaned it up only to find it worse this morning! The police are no help. They can't stake out my garbage can, or even take prints. These aren't your everyday criminals either. They didn't just knock over my trash, they went through it. I don't know if they were looking for credit card numbers or bank statements but we are real careful with those so I feel safe. But they did find some dirty diapers which they some how "cleaned". Now I am all for recycling, but I do believe there is a line which you do not cross. Diapers cleaned by criminals from the trash can is somewhere WAY beyond that line. What is a man to do to secure his home for his wife and child?
