Thank you, Carana, for this interesting document that shows countries have different views on the topic. However UE countries have managed to agree on a hotline nb and cooperation which is really a progress. You've read that one of the difficulties concerning a specific offenders' register is it has certain repercussions on sex offenders' privacy and reintegration into society.
Had Portugal an abduction alert device in 2007 (as France), it couldn't have be used in Madeleine's case, since one of the criteria is proven or highly probable (breaking in) abduction.
Well, I guess these situations need to be considered on a case-by-case basis.
I don't see why an alert has to be restricted to proven abduction. Sadly, not all abductions involve someone being shoved in the boot of a car observed by a bystander who happens to have a smartphone to take a snapshot of the car and licence plate. Or, at the time, might have needed to have a pen and paper at hand.
A
missing alert might be more appropriate in some circumstances, namely when there is a real fear that the missing person could be in serious danger, with precise information that the public should look out for.
I'm thinking in general, not just about Madeleine's case.
