Interesting comments there.
I wonder how people (we) would react if we were told the truth?
EG "This is Homeland Security. We would like to go to Red Alert- but we don't have the money to do so, so we are leaving it at yellow but trying to simulate Red in the cities.
By the way, duct tape will not be necessary given the current threat information coming in.
Your entire country is targetted for destruction by crazed jihadis wielding bios,chems, and nuclear weapons. Probably sooner rather than later. Could be tomorrow.
Please read "What to do with less than 3 days until a Nuclear attack" for further instructions.
But stay calm, and keep shopping at Walmart."
