Police departments on alert, patrolling in pairs after Baton Rouge shooting

“There are to be no solo foot posts citywide,” the New York City Police Department said in a bulletin to law enforcement personnel. “All uniform members of service shall arrive and remain on post together. All meals and personal breaks will also be taken in pairs.”

Chicago and Boston also told officers to patrol in twos.

In an earlier tweet, the Boston Police Department instructed officers to “use caution and remain vigilant in their patrols.”
