The security system is sort of like a water system. Few over-spend on maintenance, and just absorb the shutdowns for repairs … as part of doing business. So as long as there are minor security breaches, the controls remain lax. But when the are greater risks of security, then the spending and inspections increase. The Algerian M. Khalil, is seeming associated with one of those security risks. And as we know, if lone-wolf or from a organised group, it is best to prevent a terror action, rather than deal with its aftermath.
