I've been trying to find instructions online, and maybe with a pic of something I saw years ago, but I can't remember how long ago or where, just that I saw it online, a way to tie somebody's feet so they can't escape even though their hands are free.
I think I can remember enough to describe it. Find two trees about six feet apart. Get the prisoner to lay down on his stomach and put his legs around one tree. You need a long rope; tie his feet together around the tree, then take the ends, and tie them to the far side of the second tree. Then the prisoner probably can't touch his feet; if he can, he still can't untie them because the last knot is way far away. (Assuming he doesn't have a knife.)
I've never done it, just read it. I think I said it right, but ask me if I need to explain better. But anybody seen that online anywhere?
