The McCanns were made arguidos, Brietta, no matter how you feel about it, and their background was used in their support. Are you denying that?
A person's background is taken into account by police officers during investigations and it's one of the 'main' reasons why Ian Horrocks thought making the McCanns arguidos was 'preposterous'.
"Firstly and most importantly, it is statistically unlikely, the main reason being that there is no family history that would point in any way to this."

The McCanns were made arguidos based on entirely the wrong premises. The same circumstances do not apply to anyone being made an arguido in Portugal today including Brueckner; a fact which you contest vehemently but for all your denial, remains just that - a fact.
The only relevance to "the McCanns arguidos" as you so deftly would have it, is that they never faced charges.
Whereas "Amaral arguido" did and was found guilty of a heinous crime. Which is an event all sceptics manage to wipe entirely from the equation.
Can you possibly explain to me why Brueckner, currently an untried arguido most certainly in the sceptic mind enjoys the right to the presumption of innocence. But the whipping boys of sceptics, the McCanns, are denied the right to the presumption of innocence despite three police forces publicly declaring for them?
If you cannot bring yourself to attempting to trying to explain sceptic logic, how about having a go at explaining why you think "McCann arguidos" is an appropriate soubriquet for you to use.
Did you come up with that all by yourself? or is it common parlance thought up by someone else in the darker reaches of the internet to where you appear to be trying to drag this little corner of ours?
