I don't think this case will have any effect on how other cases are approached.
Surely it should make a difference in Portugal G. For instance AFAIK it was the GNR who decided when to contact the PJ when a child was reported as missing. IMO any report of a missing child should immediately be conveyed to the PJ detectives. This would eliminate the recurrence of what happened to LC when - on approaching a GNR officer whilst searching for her daughter - was told to go home and if she hadn't turned up by morning to come into the police station. I can't remember how long it was before the PJ were informed by the GNR, but I believe it was quite a long time.
In the McCann case I believe it was also some time before the PJ were informed.
Surely that is something that could and should be changed - as it affects the Golden Hour.
(The above is from memory - so am happy to be corrected if I've got it wrong)
Happy New Year btw. (and to everyone)
