It's simply nonsense to imply current rules are ineffective. Staff, crew and members of the public at every stage are empowered to trigger a test, the consequences of failing which are immediate and severe. This case, far from depicting an "honesty box system" demonstrates the robustness of the system. It works! A fact backed up by the total absence of incidents and accidents caused by alcohol. The 100% screening so misguidedly being sought would be very expensive, almost certainly wouldn't have prevented this incident and contribute nothing to safe flying.
