Watch List Resources?
Given the failure of potential terrorist watch list protocols to prevent the recent Martin’s Place incident, what more might be done?
Quite apart from metadata collection and collation, some form of automated video monitoring technology gives the best chance of interdiction at potential focal points of attack – prominent public places, transport hubs, places of National or religious significance… One problem is the grainy low resolution CCTV images we are used to after events. Clearly this ought be upgraded to higher resolution, automatically focused (or using rapidly sequenced multiple focus planes), and use of multiple camera views for 3D rendition all for much higher probabilities of automated recognition. Facial recognition databases, including the camera systems at immigration gates and driver licence bureaux, would need to be upgraded too to best leverage such camera and processing initiatives.
The limited number of people on watch lists should make it logistically possible to automatically raise an alert to responders when a person or persons of interest approach a natural target location, particularly with a high probability score given the technology underpinning a particular source.
So, security agency policy makers, broaden your focus beyond Metadata. That will be incredibly expensive and require exorbitant investment in human resources to leverage the results. More cost effective might be deploying technology at the places we need to interdict actors should they seek to do harm.
