Hi, FW_Cat, I'll fully admit I haven't read the WS policies recently myself. I know this due to mod/admin posts I've read and also because I interviewed Tricia for Ozy.com a couple of months ago. She was very specific that sleuthing an individual unnamed by the mss or LE was not allowed for the reasons I shared (this wasn't part of the article, just a conversation we had).
And as far as the serial killers, yes, I'm sure they have families, but I think its fair to argue that convicted killers are already named by LE and the mss, and are therefore fair game.
