If I had one like that in my back yard and didn't shoot him when deer season came, there is no doubt that my Amish Dutch neighbors would. That is assuming they would even wait for the season to start.
I never ever thought I would post my property but the Dutchmen broke me when they decided they would let me stay on my stand (on my land) during one of their drives on the first day a couple years ago. Last year my neighbor told me he saw about a dozen preparing to put on a drive in the thick stuff across the road from my house while I was out hunting in another county. I said, "Apparently they didn't see the "posted" signs every 100 feet." He replied, "No trespassing signs don't bother those boys a bit." I thought about buying some mine field warning signs I saw at a gun show recently but the guy didn't have the mines to go with them.
