Not sure about court proceedings but I did read an article stating he had reported someone for trespassing on his property. I can try and find it again if you think it would be helpful.
I would be interested in that - I don't recall seeing that before.
By the way - how creepy would that be for the trespasser to realize he/she might've been lurking around on a SK's property!
If someone has a specific county/locale in mind, let me know and I don't mind linking to public sources for court docket searches, or the lack thereof.
ETA:
If it turns out NMF is a SK, I think he went through an evolution or two. I think the Backpage.com thing is relatively new. I say that because his online presence - and I am seriously skeptical of the transvestite line of thinking - is almost nil (even if you include the BJRoss/Dusty Fog stuff). Unless some new information pops up about an online persona, I just don't think he had one.
There are 2 main AR-15 forums, ar15.com (arfcom) and M4carbine.net. (Sorry idoctor, I was sandbagging you a little bit with the firearm stuff.) Of course, they attract people interested in other firearms, and have developed communities within the forums themselves. So far, it doesn't look like there is any link to the known aliases of NMF.
If he was REALLY into firearms, and had any sort of internet proclivities, I think he would be on one (or both) of those. There are also Nevada and Oregon based shooters forums, and there does not appear to be any link to him in those usernames.
