According to a survey of policemen , cited on the Wright programme this morning, 56 per cent of officers would resign the force if ordered to carry a gun. If that is accurate, we'd have difficulty arming officers.
Capital punishment for murdering a policeman on duty or a prison officer by a serving prisoner, among a few murders, was the penalty once, to the exception of most murders. Does anybody think that a pscyhotic or hardened criminal really cares? Podolsa was hanged for shooting a policeman in cold blood. He wasn't deterred and nor were others. But it's impossible to answer the question; there may have been someone who thought that they wouldn't kill someone because they might hang for it but they would if kill them if they were sure to get life.
Trouble with the death penalty was that whether you hanged or not depended on the state of digestion, as it were, of the Home Secretary. If he thought the hanging would be popular, you hanged, if unpopular you wouldn't, and there were as many ways of thinking as there were Home Secretaries.
