Red Alert = Martial Law?: If the nation escalates to "red alert," which is the highest in the color-coded readiness against terror, you will be assumed by authorities to be the enemy if you so much as venture outside your home, the state's anti-terror czar says. That's in New Jersey.

"Red means all noncritical functions cease," [anti-terror czar] Caspersen said. "Noncritical would be almost all businesses, except health-related."

"The state will restrict transportation and access to critical locations," says the state's new brochure on dealing with terrorism. "You must adhere to the restrictions announced by authorities and prepare to evacuate, if instructed. Stay alert for emergency messages."
