A new police unit equipped with military-spec assault rifles has begun patrolling the streets of the Australian city of Sydney, in a move that is the first of its kind in the country, reducing the number of witnesses to the deployment of heavily armed security personnel, according to Reuters. The establishment of the "Armed Response Command" came in response to the attack on Bondi Beach last December, in which 15 people were killed during a Jewish religious celebration following a shooting by two gunmen.
