We saw the movie the Kingdom. In it right after a sucide bomber blew up some Americans a second explotion devastated the survivors and their helpers as it was in ambulance. It is like plan B to terrorists - it discourages those engaged in rescue operations and hence the good people and it also ensures that more people are killed as if the first bomb doesnt get enough people, the second bomb gets the crowd after that. To the victims and the family bombing of rescue operations sends a chilling message of hopelessness and hence amplifies the terror message. I think the security agencies now need to be ruthless with the terrorists as these terrorists have now violated the last iota of humanity and deserve to be treated as target practises.
