Red Alert is Martial Law in New Jersey

According to this story, New Jersey will declare martial law if the Department of Homeland Security escalates the terror threat to "Red".

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.

No word on other states yet. The Oregon State Police have some definitions and guidelines yet nothing specific. Read the definitions at http://www.osp.state.or.us/opss/.
