Criminals in this country have never used firearms as a matter of course. That fortunate state of affairs has tended to shroud the fact that New Zealand and the United States are virtually alone among Western nations in not having registers to try to ensure every gun is tracked.
The danger inherent in this is implicit in the Police Association's alarm about an apparent change in criminals' attitude and behaviour. Firearms, it says, are becoming "ridiculously easy" for offenders to obtain, and are being used almost daily in confrontations with the police.
The union wants an official police inquiry into where the guns are coming from, and says the issue has been neglected by the top brass. Police on the street, it says, are "in no doubt that the number of weapons out there is on the increase and gun-toting crimes are becoming the rule rather than the exception". This, it adds somewhat needlessly, is "an additional risk that police don't need".
For a long time, it has been apparent criminals can obtain guns relatively easily. Some may be imported illegally and some are traded, but the major source is theft from the residences of firearms licence-holders. The richest pickings are from the arsenals of collectors.
The outcome is that the police have no real idea of how many firearms - legal or illegal - there are in the country. So poor is the record-keeping that there is not even a national register of seized guns. All the Police Association can see is that offenders seem to have ready access to firearms.
