Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.
Just get rid of it without incident and move on. I think that's the best idea.
From my experience, the police won't do much b/c years back when my parents had private property, people dumped bags and bags of trash, cut down trees ( once we caught someone and we had tag numbers), we had evidence from the trash b/c the people were so dumb they threw their mail away and we had their names and addresses. Basically nothing will get done. If your husband is really insistent, it also comes down to eyewitnesses.
I think as mad as you are, try and let it go. You don't want to feud back and forth w/ these inconsiderate dolts.
