Much as I would like to join in with a lively debate on some of the issues already being high-lighted in this incident, suffice as to say this is a major crime scene and a major criminal investigation is underway. It is wholly in-appropriate for those in the industry to speculate on any of the issues that drive such a devastating criminal act, and vitally important that the investigating team are allowed to carry out their work without distractions.
It may however be the case that a number of Police units within the UK take a long hard look at there own security arrangements, given the nature of this catastrophic incident.
