Eric,
If you don't mind....where did you find that story?? There are several ways to test a system like this once it is in place, and just to, right off the bat, test it with a semi live scenario might not be the best idea.... I think if they went through a couple of dry runs that were advertiseed probably would have been better.... and then do a surprise, unadvertised one, then everyone would have been more prepared for a mock incident...or a real one for that matter.... Just a thought...
Thx, Jeff
