FORMER West Yorkshire police chief Keith Hellawell believes police killers should be hanged.
The retired chief constable also believes the death penalty should be restored for child murderers and terrorists.
He spoke out hours after West Yorkshire Police launched a huge manhunt for the gunman who shot dead one officer, badly wounded a second and shot at a third.
Pc Ian Broadhurst, 34, was gunned down in Oakwood, Leeds, on Boxing Day afternoon.
He was shot by a man after police approached a stolen car.
Colleague Pc Neil Roper, 45, was shot and wounded. Pc James Banks escaped injury.
Mr Hellawell - who was an assistant chief constable the last time a West Yorkshire policeman was shot - said the call for the death penalty was not a kneejerk reaction.
The Examiner columnist said: "I had to deal with the shooting of Sgt John Speed back in 1984 and I remember the terrible task of speaking to his widow and family.
"I think we should bring back hanging for the murderers of police officers, for those who kill children and for terrorists.
"I have held the views for a long time and clearly after the events of September 11, when we saw the horrors of terrorism, and the Soham murder trial when child murders were to the fore, we must look at sentencing.
"Here in West Yorkshire we now have a police officer shot dead when he was doing his normal job.
"Arming the police is something people say should be considered but it as not as easy as it sounds.
"We cannot suddenly change the rules and make all officers carry firearms, as they have to give consent.
"And secondly, even if it was considered, it is important the people who carry arms have the right psychological make-up. It is not simply a question of holding a gun and shooting straight.
"From the reports I have heard about the tragedy in Leeds, it would seem no-one could have contemplated what happened. I am sure we do not want to have the US style of policing where every incident sees police with guns drawn, pointing them at the driver of a car."
