Couple things.

Do you know for a fact that these events actually happened? Some possibility that he could say these things happened to bolster any denial for others on his property. Just saying.

Now if these things did happen then you need to face the fact that there may be sililar suprises awaiting on the property you are on! Something like a wire in the early darkness could be a bad wake up call!

Why he didn't get LE involved is anyones guess. But sometimes people want to deal with things themselves and in their own ways.

I personally would get the law involved. I would also do my own detective work such as keeping a sample of the wire, pay attention to the way it was tied or attached to the trees, look for prints in the dirt around the trees and on trails. Any prints not known to belong I would photograph. Stuff like that.

You need to be very careful from here on out. I mean sneeking around the deer woods takes a keen sense and gentle foot but it blows that you now have to act like there could be a claymore trip wire anywhere and your next step could be your last.

Now of course I cannot condone such behavior, but if the pranster should be caught, it would be hard to not bash some teeth out. (Of course people are known to trip from time to time. I mean who hasn't ever tripped?)
