As we go about our daily lives, we should look for things that just don't belong or are out of place. As Peggy Noonan wrote, We're All Soldiers Now. This isn't a time to hide under our beds or quake in fear. It is a time to watch for things that are out of the ordinary.

I do discount the idea mentioned in Noonan's article about buying gas masks. Having been trained in NBC (nuclear, biological, and chemical) warfare in the military, I don't think any of those masks would be much good in a for-real chemical attack. Many chemicals are designed to be absorbed through the skin. Unless you have a full NBC suit, the mask by itself wouldn't do much good. Frankly, I'm not going to bother with any of that.
