And I have to ask, since I did this for ten years in pretty serious conditions, involving among other things real bullets whizzing by... your opinion is based exactly on what? Mine is based on actually having done the job for ten years, and having a few rashes of false alarms, where yes, we laughed it off, where people like you could not see us. We also used to really laugh it off after a major Multi Casualty Incident, fire, HAZMAT incident or shooting\ shootout. But hey, what would I know?
But seriously, when they finally find a real bomb, the mood will quickly shift. So far, they have not. Which is a good thing, and a bad thing. It is a good thing they have not, and a lot of folks are going for the really dark humor, you might not get it, but I can count on it. It is a bad thing because yes, even EMS and Bomb Squads and cops can get complacent with the boy who cried wolf too many times. That is the down side of this.
The other down side, is that on a very serious matter, somebody MIGHT be testing the response to find holes. That is the OTHER down side.
But if you think a lot of these folks are not doing what they are doing to decompress, I gotta a wonderful piece of beach front property in AZ... I speak, on this one, from real life experience.
