Earlier on in the investigation Scotland Yard requested access to bank accounts and for permission to search accommodation associated with these three arguidos.
Their requests were refused by the judiciary.
I fail to see what the problem is.
When Robert Murat was an arguido there was no compunction about checking him out thoroughly and searching his home.
What is so different about these guys?
The small difference is SY did not interview Murat, check him out thouroughly, or search his home because they had no jurisdiction to do so.
This is a Portuguese police force and perhaps they did check these people out, and rule them out. They did re interview them in front of the SY so what more can be done?
If Kate can refuse to be re interviewed,refuse to answer basic questions, and do a no show for a reconstruction then why should any one else who may not have been involved be dragged screaming to account for THEIR whereabouts etc.
