Technology will not help when the problem is on the human side.
1. Suspects (at least the key ones) were known to the police. Data was available, humint in both Belgium and France failed to draw the lines between the dots.
2. Technology has failed to spot fake passports issued to same individual. It is laughable that Greece which pretends to be in Shengen did not spot a duplicate passport and Serbians picked up the fake Ahmad Almohammad(s) without having access to the Shengen database.
So for starters - remove Greece from Shengen until it sorts out its human + technological side to Shengen requirements. In fact, I do not see how they were admitted in the first place without having an electronic birth certificate register till 2 years ago (something which the supposedly backwater Bulgaria and Romania has had since the early 1970-es). As a side effect this will force full reprocessing and readmittance of all refugees including checks of documents as they should be done to the Shengen standard.
