Yes, I think that was it. They simulated several terrorist attacks around the area including swat going in and clearing the school and transporting the kids to the stadium.
DHS Grants included 100 different agencies. Fake parents were given a script apparently, and pictures and news media were not allowed.
They also had a drill in Muskegon Michigan which simulated attack on school bus. Scenario was that a wacko group attacked public school bus, because they believed all children should be home schooled - so they smeared homeschoolers in their terrorist theater drill.
I think that was it. Thanks for the link. I just skimmed over a couple of the articles, but I’ll read more later.
