Whatever the truth about the horror, however, we must not lose sight of one thing, and that is the personal impact of the tragedy not just upon relatives but upon everyone involved in the failed rescue bid and subsequent investigation.

Firemen were, of course, on the front line in dealing with the emergency and witnessed some horrific sights that are likely to stay with them for a very long time.

However, it is not just fire crews that will have been affected. Ambulance personnel, police officers, forensic investigators and neighbours - young and old - will all have been exposed to severe emotional trauma.

Children and staff at the local school, which sits very close to the charred remains of the family home, will have a constant reminder about the tragedy.

The authorities, who supported the people of Omagh so magnificently after the 1998 bombing, must make sure that emotional support is available to everyone who needs it, not just in coming days but for weeks and months into the future.
