NYPD Cops Given New Terror Guidelines: Report

New York City police have been given new guidelines on how to handle chance encounters with terror suspects.

That's according to the Wall Street Journal, which reviewed an August 20 police memo outlining the instructions.

Officers will receive one of four "handling codes'' if they encounter someone listed on the National Crime Information database during a routine traffic or other stop.

Code One indicates the person may be associated with terrorism. Code Two suggests the person is part of an active terrorism investigation. Codes 3 and 4 indicates the person has been identified through intelligence as having ties to terrorism.

In each case, officers are instructed to contact the department's Criminal Intelligence Unit.

But they are told not to arrest the person unless there is probable cause to believe they broke the law.
