It would seem that they fear something is up, for the big bueracratic "system" to make such massive/swift changes makes one think that something is indeed "rotten in Denmark".
I read many of your posts that weekend...very disturbing happenings...be safe out there!!
Nothing happens that fast but I have to admit I felt very safe at the game. My daughter and I were carrying sweatshirts and they had us shake them out. You could not carry any bags into the stadium. Saw cops everywhere, concrete barriers on the sidewalks and the oval with a lot of cops after the game directing traffic. Usually it is every person for themselves but the cops were directing traffic after the game. I have been complaining for years about lack of cops directing traffic but they were there Saturday night.
Your statement about "rotten in Denmark" fits this situation completely.
