What Charlie said.
This all started with my claim that John Douglas's credentials were impeccable. (High falooting language, I know....)
The Guy Paul Morin case was, first and foremost, bungled because of what can be called outright police/prosecutorial fraud. Perhaps it would be better for Douglas-critics to point out where Douglas participated in fraud.
Profiling is like anything else, as Charlie suggested, it does not replace investigation. It seems one of the bits of chicanery that the Morin investigators played is calling in Douglas when they already had narrowed their sights... were themselves engaging in investigative myopia that tends to be the hallmark of wrongful prosecutions.
And like anything profiling has its limits. I'd read about the Steven Truscott case in Canada in the 1950s, where teenager Truscott was convicted mainly on the, then, not-well-understood science of stomach contents analysis. The issue back then seemed to be that lay-juries regarded science as voodoo, and as accurate "just because it was science." Lay juries would be prone to even ignore the caveats the scientists themselves would bring because of something similar to the CSI-effect.
So... what does any of this have to do with John Douglas and Douglas Preston writing a book about "The Forgotten Killer", about Rudy Guede in the horrible Meredith Kercher murder in 2007?
Let me put it this way - on the one side there is John Douglas.... proclaiming Sollecito's and Knox's innocence. On the other side there is an essentially anonymous Wiki by a man named Edward McCall.
Last night I spent the same amount of energy going through the bona fides of Mr. McCall, his educational background, his law enforcement training, his experience in the field, his claim about access to original transcripts.... as others have (apparently) done in ascertaining what to make of this "impeccable credentials" claim about John Douglas. It was a short investigation!
Did you know that no less that respected journalist Andrea Vogt cites this anonymous-Wiki as the key to understanding this horrible murder?
I, for one, would love to be able to expose this Wiki as drawn from and assembled by people with "impeccable credentials", but you know what? No one knows who they are!
John Douglas et al. puts himself out there... here's my work, go to it. Criticize it. Peer review it. Tear it apart in some equally anonymous JREF discussion group. Make my day.
Strangely, this willingness to be reviewed settles many troubled hearts in discerning what's what in horrible murders.
Edward McCall? Even the JREF mods cannot invoke rules in censoring criticism of him because, no one knows who he is! If he's a poster here on JREF, no one knows which he is.
At least Crini is willing to put his name to asinine theories of pooh in toilets leading Meredith to become such a bitch about cleanliness, that it leads to her roommates rising up against her. (Note: Crini's theory is a completely unfair, and venomous attack, essentially, on Meredith's character! Of course Meredith did not do that. And she's the victim here!) But Crini is putting it out there to be reviewed....
..... which is the question CoulsdonUK says is the one which interests him. What will Judge Nencini put his own name to in the forthcoming motivations report? Will Nencini buy into this character assassination of Meredith? Or will Nencini write about, as directed by the ISC, that Meredith was at least initally a willing participant in a sex game until it went wrong?
If Nencini convicts tomorrow, maybe the good judge will be hoping that no one will read his motivation for doing so.
