I understand your frustration. I moved my family (actually sold my home and moved to a different town) due to trespassers. I put up signs, but they were torn down or uprooted and thrown on the lawn. I also called the police, and they said that they would be as helpful as they could be, but unless they caught someone in the act then they couldn't do anything. The police said that if the trespassers were aggravated then they may destroy property, and that without solid evidence prosecution was unlikely to go anywhere. So if you irritate someone and "get a brick through your window" (this was the example the police gave), even if you get a picture, it won't prove they threw the brick. The solution was to move.
