The town of Kennesaw Georgia enacted a similar town ordinance, If you did not own a gun in the household, you needed to pay $300.00.
The $300.00 figure was derived by figuring typical annual cost's for ammunition, targets, and gun cleaning supplies. But this was also back in the early 1980's.
The crime rate in that town was way out of control until that ordinance passed, and it fell off dramatically and stayed there, the criminals decided they would find an easier flock to prey upon than the armed citizens od Kennesaw GA.
I have never seen the brady bunch bring up that bit of history in their spewings, I wonder what bullschitt they would try to make up to twist or cover this success story down there.
I think we could get a small WI town to enact a similar ordinance, it would make the national news and forward our position dramaically.
