Be Afraid

From CNN.com:

The FBI bulletin repeated for local authorities a previously released list of indicators often associated with suicide bomber attacks overseas. These include:

- Irregular, loose-fitting clothing not appropriate for warm weather, possibly with "protruding bulges or exposed wires" or a noticeable chemical odor

- "Sweating, mumbling (prayers) or unusually calm and detached behavior." In addition, people who refuse to show their hands, possibly to conceal a detonator

- Disguises, including military, police, medical or firefighter uniforms or someone posing as a pregnant woman

- Large or heavy baggage not appropriate for the location, such as a big duffel bag carried into a restaurant
