Apparently some unarmed policemen followed in a commandeered car, but the gunman was a local taxi driver and managed to carry out his intentions and get away to eventually take his own life.
As Shotgun Franklin surmises, none of the local inhabitants were armed, so were unable to affect the result, and presumably no-one was willing to sacrifice his vehicle to bring him to a halt, from his mobile massacre spree.
( He was driving around, shooting out the car window.)
At least our new Prime Minister is saying that there should be no knee-jerk reaction, until all the facts are known.
