The gun control controversy is only the latest of many issues to be debated almost solely in terms of fixed preconceptions, with little or no examination of hard facts.
Media discussions of gun control are dominated by two factors: the National Rifle Association and the Second Amendment. But the over-riding factual question is whether gun control laws actually reduce gun crimes in general or murder rates in particular.
If, as gun control advocates claim, gun control laws really do control guns and save lives, there is nothing to prevent repealing the Second Amendment, any more than there was anything to prevent repealing the Eighteenth Amendment that created Prohibition.
But, if the hard facts show that gun control laws do not actually control guns, but instead lead to more armed robberies and higher murder rates after law-abiding citizens are disarmed, then gun control laws would be a bad idea, even if there were no Second Amendment and no National Rifle Association.
The central issue boils down to the question: What are the facts? Yet there are many zealots who seem utterly unconcerned about facts or about their own lack of knowledge of facts.
