I use the video camera on my cellular telephone to record the encounters. I have the trail cameras going off like crazy, but I want, for potential legal recourse, to have a record of what _I_ said, my tone and demeanor, especially when dealing with kids. As much as I want to record what they say, their vehicles (4 wheelers mostly), and their identities.
I have no need for an irritated parent to go off on me because their child lied to them about my approach, demeanor, and what I said. I can play back the tape and they can see for themselves.
But again, both my attorney and the sheriff said it is in my best interest to record all confrontations and interactions.
