Today, the subject of terrorism is like the action of a latent volcano. It’s constantly boiling below the surface, coming to the top when an act of violence is attempted or when new countermeasures are implemented. Recent examples were, on the one hand, the attempt to use large toner cartridges to carry explosives, resulting in restrictions on the transportation of such cartridges and, on the other, the deployment of graphic body- scanners and the implementation of invasive, intimate body pat-downs.
