C'mon -- I'm not saying that at all. You don't think there was anything wrong in the guards in the buildings telling people to stay in their offices? Or the public address announcers saying that? Obviously, the people who recounted this incidents didn't listen to them, or they wouldn't be able to tell about these incidents! But it's morally irresponsible, to say the least, for the people in those buildings to have been told to stay put.
