certainly do not go take his feeder.
serve a trespass on him, easy to do...you can set it up with the Sheriff.
put a cam on your cam...a good hidden one with no flash, and preferably one that runs video.
He should be very luky you didnt think he was some kind of game animal
you should have called the 5.0 when he was climbing your tree stand the 1st time.
lawfully you can disarm him and keep his stuff. ( i.g if you tell him to drop his stuff, and then ****** him to the gate to meet the cops...what ever is on your land is yours.)
