Mr. Jim Keogan:

Subsequent to each night of a concert, the representatives of the various bodies and organisations involved, including the Garda, come together for a briefing on the good and the bad parts of that night's event to identify any issues that need to be addressed for the next night. That happens at the end of each evening of a concert. The Senator was referring to the formal debriefing that takes place within six weeks of the event's conclusion, which identifies major strategic issues that would inform management plans for later events.
