Terrorist Scare at the City of Seattle

It is a little disheartening to be in a meeting at the City of Seattle skyscraper and hear over the load speaker:

"Due to heightened security, only the main entrance to the building is open. All other entrances and exits have been closed."

(That was not the exact wording, but that is definitely the gist of what was said). I doubt that I was the only one in the building who had a chill run through them after hearing this message.

Anyway, it turns out the scare was just because some nut left a box and a fire extinguisher at the security desk, but that is not what I imagined as I tried to concentrate through our meeting (up on the 39th floor).
