while this is despicable we should not gloss over the fact that if people are disturbing someones private property there is the other side of this as well.

It is the society that has grown not to respect private property (the fact that it barely even exist anymore is a good example of that), dirt bikers and cyclists menacing fields and forests everywhere. Sure there's plenty of bitter owners who then do crazy stuff like that (i've seen photos of wires at neck height for bikers) but we must also acknowledge that disrespecting peoples property is not ok and should not be waved away.
