First is the problem of the current gun stock in the US, a stock in excess of 200 million guns. Second is the problem of interdicting guns being smuggled into the country. For years the government has been trying to halt the flow of illegal drugs into the country and they have completely failed to even make a dent in the supply. Thus, why should anyone believe that a governmental interdiction could stop the flow of illegal weapons. Third is the problem of manufacturing guns within the country.
Every machine shop has the capability to produce firearms.
For example, Norway, the European country with the highest per capita private firearm ownership rate has the third lowest murder rate of all European countries. In 1971, after decades of increasingly stringent gun control laws in Canada, the US murder rate is 4.3 times the Canadian rate. In summation, cross-national studies intended to show the positive impact of gun control, completely fail to do so. Another issue conveniently ignored by gun control propagandists are the number of times that guns are used by private citizens to stop crimes. First, this statistic will be examined, then some more meaningful ones will be derived.
