Just a touch off topic:
I grew up as an Army Brat, and as an Army wife.
I grew up with terrorist attacks on/near military installations in Germany.
I remember "Yankee Go Home!!", and militants attacking.
I remember the Baader Meinhof Gang and the Red Army Faction.
I remember NEO briefings. (non-combatant evacuation operation )
I remember so much more.
All these things make me who I am and have molded how I think about terrorism, and how I think about the USA and our freedoms.
Unfortunately,(rather,Fortunately) there have been and will always be bomb threats that are hoaxes. These are terrible times, and terrible people.
Discerning what is a threat and what is not, has been proven to be difficult under certain situations, particularly, since the San Bernardino incident isn't that far away from Los Angeles, and the Timing of it, as well.
Similarly, the Planned Parenthood killings that happened in November in Colorado Springs on Centennial BLVD, well, with the bomb threat yesterday on Centennial at the Comcast building, I can certainly understand the evacuation, even though it was found to be a hoax.

So how do people treat bomb threats?
Perhaps most are hoaxes, but in this day and time, which ones do you pick and choose??
A judgement call, and hope it is all ok, I guess, if one doesn't react to it.
It IS easy to react to it, because these are scary times, Unfortunately.
Bad things DO happen.
IMOO.
