Somewhat Alarmed

Okay, so our whole day has revolved around talking about these supposedly imminent terrorist threats. They are searching backpacks at the entrance to our neighborhood and we have been advised to stay off the main streets, not to travel, and basically not to do anything that could be considered remotely normal. I usually think that people are overreacting to situations like this and continue doing what I was doing. The number of police around town is really scary though...
