"The gravity of gun crime cannot be exaggerated. Guns kill and maim, terrorise and intimidate. That is why criminals want them; that is why they use them; and that is why they organise their importation and manufacture, supply and distribution. Sentencing courts must address the fact that too many lethal weapons are too readily available: too many are carried; too many are used, always with devastating effect on individual victims and with insidious corrosive impact on the wellbeing of the local community ... as a matter of sentencing reality, whenever a gun is made available for use as well as when a gun is used public protection is the paramount consideration. Deterrent and punitive sentences are required and should be imposed."
