so your question is "what laws are being broken" ?
oh it's criminal. the crimes would include trespassing, harassment, destruction of property.
i am sorry your police department does not intervene.
try contacting the District Attorney directly and see what they can do
it is up to the DA to decide based on your facts which direction to go. if you have other neighbors who are also harassed and/or know first hand what they are doing, that is proof - as well are the pictures, and videos you have
you are welcome. thank you and good luck
