The idiots demand that government take care of the squatters elsewhere.
If the owners discover spines, they need to fence their property; post “No Trespassing/Violators will be Prosecuted” signs per State and local statutes; and, have a process server deliver dated “You are trespassing/leave my property within 24 hours” notices to all the squatters. Once the 24 hours has past, have police evict the squatters. Press charges for trespassing and destruction of property.
Next, assuming shooting is legal in the location”, post signs advising that: “The Owners use this property for target practice, so Stay Away for your own Safety!” Then blast away at varying times daily.
In the full NY Post article, she says she got a quote to put a chain link fence around the property, but it would cost $50,000.
