Signs of the times, special New Jersey edition

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.

“This state is on top of it,” said Sid Caspersen, New Jersey’s director of the office of counter-terrorism.

Caspersen, a former FBI agent, was briefing reporters, alongside Gov. James E. McGreevey, on Thursday, when for the first time he disclosed the realities of how a red alert would shut the state down.

A red alert would also tear away virtually all personal freedoms to move about and associate.

“Red means all noncritical functions cease,” Caspersen said. “Noncritical would be almost all businesses, except health-related.”

A red alert means there is a severe risk of terrorist attack, according to federal guidelines from the Department of Homeland Security.

“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.”

Okay, then.
