I would advide you to keep your Troll alerts GENERAL and not personal. I've already got one of mine pulled by the AM as a personal attack because I blew up at the particular troll operating here today.
As for the case I really think that the jig is up for Michael and Felos. Even if they do kill Terri there is so much information about the case floating around in the "wild" now thanks to us FReepers that it may only lead to a murder trial for them.
Trolls are believed to be morally dead. They can neither see nor hear nor feel any moral responsibility. They are utterly unable to experience either compassion or repentance.
Still, it is best not to flame them because we should always err on the side of caution. Once or twice a century, one of them might wake up and see the light.
