A gun bill drafted by Rep. Jim Howell, R-Derby, would make it illegal for cities to use local taxpayer money for gun-buyback programs or to destroy guns that had been confiscated. Kelly Arnold, the Kansas GOP chairman, said gun-buyback programs are an ineffective way to combat street violence and illegal guns. Maybe, maybe not. But why is it the state's business whether local officials use local money to buy guns from willing sellers? Why it is the state's business whether local officials destroy guns? It's more big government from the conservatives in Topeka.
