This is to ease Mama’s concerns a bit.
It seems I got it slightly off-beam last night. When you get a “going to level 5” message, a phone call saying things are going down bad in Delta area and the guards staying for the night (on a piece of carpet on a concrete floor), I assumed that things were going bad.
It seems the Delta thing was nothing more serious than any other rock night, and when you have a bevy of security forces with decent equipment, at the end of the day, they ought to be able to dampen down things, and obviously they did.
Today seemed perfectly calm and for a level 5 (whatever that is), no problems at all.
So sorry for raising the sweat levels, except if you live at Delta 4.
