This may or may not be relevant. I once spoke with the Intelligence Chief of the Marine barracks that was bombed in Lebanon. He was giving briefings to other officers and intelligence people on what transpired. After 6 months he was still very shaken with guilt. He said that the week before the bombing they had 1300 messages (if I remember right) warning of various "imminent attacks". In that kind of environment, it's almost impossible determine which one is real.

The only thing more useless than an alarm that never goes off is an alarm that ALWAYS goes off.
