New Jersey Gov. Chris Christie, who suggested that the NYPD's intelligence operation in Newark may have been "born out of arrogance," says surveillance of people when there is no suspected wrong-doing should be decided on a case-by-case basis.

Christie, the former U.S Attorney for New Jersey, says the NYPD should have notified the Joint Terrorism Task Force that it was monitoring Muslims in Newark.

Besides ensuring that police weren't duplicating efforts, Christie says the coordination would have provided a way for police to keep a lawful check on each other.

On Wednesday, Christie also shot back at New York Rep. Peter King, escalating a war of words between the two about the NYPD's operation and the extent to which other agencies should have been briefed.
