IFFFFFF there is a connection, whoever it was may have had a preference for British children. However, this may not be the case at all as each country will decide on what information can be divulged.
There is no way of knowing, for the moment, whether families of other nationalities had also been targets and have reported incidents which the UK aren't authorised to divulge.
I agree.
The fact that we know about British victims arises as result of Madeleine McCann's disappearance and just as the British diplomats were aware of the attacks on British children it is possible consulates of other nations were aware of assaults on their Nationals.
If British children were the only victims it raises the supposition that there was a British connection (or preference) somewhere in the picture, perhaps an ex pat employee of the agency which arranged holiday lets, an ex pat paedophile or someone working in supply of services be it catering or car hire?
Whatever, someone with a British connection which may be a tenuous one.
There are risks associated with taking children on holiday; swimming pools and balconies immediately spring to mind but venues where children may be subject to assault or disappearance might be considered a risk too far for some parents.
The Algarve with its climate, people and proximity is the perfect choice for holiday makers but as well as welcoming the income arising from tourism the authorities must pay much more than lip service to their security.
Funnily enough I think that rather than damaging the tourist economy the renewed and determined investigation to discover what happened to Madeleine McCann reflects well on present day Portugal.
