Charging into the new medieval period
The unrecognized problematic of the current charge of the "developed" world headlong rush into a renewed feudalism is that the banana comed with the 300lb gorilla attached.
In a hyperreal world dominated by simulations, including the simulation of threats to security (from simulacra), the model is confused with reality. The model in this case being the only extent model available - the historical frame of the medieval period. Think Crusaders, for example.
Notice that the events of 9/11 coincided with a contemporaneous simulation of preparedness - there a presented simulation was used in a sophisticated interplay with actual events to disguise the mechanics of erecting a new simulation (the future "war on terror"). But since the long-held distinction between knowledge and (supposed) objects ("out there") which cause knowledge has disappeared in the hyperreal, the new Crusaders are obliged to accept the philosophical baggage of the period, as there is no criterion for its elimination. So the medieval revival also features a resurrection of ideas about "universals", and a repeat polarization of views about them into the scholasticist philosophies characteristic of the period.
But rather than read a philosophy book, have a laugh with Eco's The Name of the Rose. Then ask yourself if it can really be the case that having a name in common with one on the "terror watch list" justifies the belief that those people must share attributes in common, e.g. suspected of being a terrorist?
Rejecting Platonism, and introducing the element of time into the picture, adds the "problem" of potential futures - ie the attribute of " may cause terrorism in the future". So the ontology of the present becomes an issue of the epistemology of the future, with the matter of criteria of justifying claims. For example try the concept of "latent terrorist", ie someone who might become a terrorist, where the operative philosophical categories are those of "being" (a present tense "is") and "becoming" (a future tense "is"), and the problem is to coordinate these in a rational way. Unfortunately, when the hyperreal dominates, some of the most useful criteria evaporate at the same time.
It would appear the watch list has decision making built in which uses proper names as one the criteria used. The system would be pretty useless if it could not accommodate the propensity of criminals to use aliases, so a properly loaded database would have to include previously used names, including any which happened to be those of bona fide suspects. So no help for those inconvenienced by the system. And no particular problem for those the system would like to catch. The system is inherently incapable of succeding in its intent for the reasons given. It succeeds in providing a sense of security which is hyperreal.
