What To Do When Your Stalker, Impersonator Is Elderly?

I have posted about this jackass before. George Frances Maudlin lives here in Modesto California. I have had some verbal battles with this ass wipe over the years. He would appear on some of the local blogs here, drunk, and would post vile stuff directed at some Christian women, me, and his own daughter. He creates socks puppets, often using my name, or something that relates to me, and my actual personal photo.
He has made personal threats towards me. Actually going as far as to say he had bullets with my name on them. Since he used a screen name, I had no recourse, according to a local police detective. He has also made phone threats towards two women, but again, it can’t be proved that it was him.
The issue I have is that if it was not a fat, old man in his late 50’s, I would have already confronted this piece of crap. Needless to say, I am old school; You talk shit and make threats, you best be able to beck it up. This is kind of a no win situation for me. If I beat the crud out of this guy, something I have a legitimate reason to do; personal threats made against me, and my property, I could be up on elder abuse charges! If I don’t, then I have zero recourse to stop this guy.
I have contacted a local public golf board which he sits on, which seemed to help for a while. But now he post under screen names, instead of using his own. I guess my biggest issue is that cyber-space allows people to act in ways they never would otherwise. Hiding behind a screen seems to make some awful brave.
So what to do? Let’s just say that I am keeping my fingers crossed that I happen to bump into George now that we live in the same town. And seeing that here in America, everybody is treated equal regardless of AGE,race, religion, or creed, I guess the old coot is due a bit of old west justice.
Say hello to George!
