Too many think the threat isn't real...or at least...that its far away from where they are living and going about their business. It is not. It is in our midst, watching and observing and planning...if you fly, go to major sports events or other large venues, you have crossed paths and been part of this "watch" being conducted by terrorists. They ARE here, they ARE active, and you are a fool if you think you've not crossed their path in public venues.
I was in the air during the 9/11 attacks, on one of the 99.9% of the flights in the US on that morning which landed safely. Yeah, there's a threat, but even though I happened to be flying at the time it was still 1000:1 against me being effected.
I also skipped class (to go shooting) while a nutcase shot several people in the building I was supposed to be in.
