We just had one of these murder-suicides at UW in Seattle. They locked down the building and people in other buildings went about their business. I was on the phone w/a friend when the news came over FNC and I told her. No police or lock down at her building at all.
The UW police are a bunch of morons...two different stories from the asst chief and chief, and the University failed to enact their own procedures. That got whitewashed too.
Remember that when the one WTC building was hit by an airplane, they didn’t immediately evacuate the other WTC tower.
