Not sure that by merely reading his site on Facebook that they would have the information you suggest. It is not as easy as that. You are also assuming that he would permit others access to personal information.

Then maybe you ought to look into it. He posted some idiotic comments about shooting up a kindergarden on his Facebook site. Some twit in Canada, of all places, came across it and, after Googling his name and finding out he lived near a school, called the New Braunfels Police and reported it. The cops freely admit that's how they found out about it. Anyway, they went and got a search warrant and a week later they arrested him. The local cops arrested him and the local judge set the bail. No grand, sinister conspiracy, just a Keystone Kops aspect to all of this that makes one want to shake their head.
