Weapons laws in Poland. Carrying a concealed handgun? [918]
My suggestion would be a gradual programme of disarmament and police reform spread over a number of years in stages.
Start with the state that has the least amount of gun crime, whichever that is and introduce a pilot scheme there.
Start by retraining the police force there in policing without guns, like the Irish Gardai so that there are armed response units available but the average guy on the beat doesn't carry a gun.
While that training is taking place, have a voluntary surrendering of arms, either legally or illegally held, no questions asked by the authorities. Let's say this is done over two years.
Then when the police are ready to roll in their new form and the public disarmed to a certain degree, do the same thing the Irish Gardai do when they suspect that guns are on the premises and send a proper counter terrorist unit to take the guns from known criminals or those likely to be harbouring guns for criminal purposes.
Then give it a further two/three years and take a look at the crime rate and gun deaths, homicides, accidental or otherwise for the total period. If there's enough of a reduction to justify continuing the scheme, then gradually introduce it across the country over a number of years and at the end of say 25 years, you should see a change. However, it has to be done in conjunction with social initiatives and other things that address some of the underlying problems that lead to this mess in the first place.
As I say, that's just a suggestion - anybody else got other ideas?
