If we had any journalists in the UK one of them might have thought to ask her what, in her expert opinion, could have produced the effect which she witnessed.
The difficulty with this is the number of cases or news stories a journalist deals with, the percentage of time one journo spends on the Madeleine McCann case (and so knowledge thereof), and the timing of when such suspicions or issues you refer to became public.
Luz tour #3 has just completed, and together with my visitor, who knows the McCann case in considerable depth, we were able to cover quite a few bases pertinent to the incident.
One of these relates to the recent 'news' by Antonella Lazzeri about the activities of Clement Freud in Luz, his watering holes and his drinking buddies. There is obviously some intelligence re the case behind this news article, and some initiative, but IMO the approach was more 'let's get a ripping yarn or two' than 'let's do some serious investigative journalism'. And that seems to be a general problem, IMO. Good story rather than hard digging for detail.
Perhaps we should have a thread entitled 'questions a serious journalist should investigate'. That sounds a bit wish-washy and a bit broad brush, but I hope you get my meaning.
It begs the question as to whether collectively we have a connection to a decent investigative journalist or two, given that some of us have the time to study the case in detail (which journalists don't) and can therefore dish up pertinent questions on a plate.
Back to Calpol, we did get confirmation from a resident in Portugal that Calpol24 became available from 3 May 2007, but not clarification as to whether Calpol50 was on the go before then.
