RE: I need Legal advise
I would persue this at the state level. When he took the shots, he wrecklessly endangered lives with a firearm which can be construed as attempted murder and with the local leo's not doing anything about makes them corrupt. He has also threatened you and your neighbors and that is TERRORISTIC THREATS OF BODILY HARM AND PROPERTY DAMAGE, which by the way is a felony offense in every state. By burning your property he committed arson and property damage. I would first file the complaint with the county prosecutor's office and if nothing comes of that then the states prosecutor office. You will get action then. As well as the local leo's and county officials that will have the state prosecutor so far up there butt's they won't want to even be associated with the neighbor.
