TRENTON, N.J. (AP) — New Jersey Gov. Chris Christie says the New York Police Department ignored one of the key lessons of 9/11 by not sharing information with New Jersey law enforcement agencies when it conducted secret surveillance of Muslim communities.Christie told a briefing Thursday that the lack of communication "seems to be an abandonment of the core lesson of 9/11."His comments echoed remarks he made Wednesday on a radio program. On the show he issued his harshest criticism yet of the NYPD's secret surveillance of Muslims in Newark, N.J., and elsewhere. He said the department had a "masters of the universe" mentality."On Thursday, the governor repeated it can be dangerous if law enforcement agencies don't share information. He says he's sure New York Police Commissioner Raymond Kelly wouldn't want to have to explain if something went wrong because of a lack of coordination.
