There’s been a lot of threats phoned in today. Maybe the sleeper cells have awaken.
Or workplace violence is breaking out all over the globe.
Al Quaeda doesn’t phone things in. They’re more interested in body counts.
Maybe they're a diversion from something bigger being planned elsewhere. You know...crying wolf multiple times across the country when nothing real is going on. Over-stretching staff to deal with bogus stuff, so that there isn't adequate coverage when the real thing happens.
