There are, for example, their widely publicized statistics on how many "children" die from guns each year. To get these numbers, gun control advocates include young people whose ages reach up above the legal age of 18 for adulthood. That way, the killings between teenage criminal gangs get counted as "children" killed by firearms, as if they were toddlers who found a loaded gun in the house.
Gun control laws might reduce the much smaller number of genuine children killed in genuine accidents. That would have to be weighed against the lives saved when widespread gun ownership reduces violent crime. But we need honest numbers and this the gun control crusaders clearly do not intend to provide.
Other misleading statistics used by gun control advocates include statistics on lower murder rates in selected countries with strong gun control laws, as compared to murder rates in the United States. What these advocates studiously avoid mentioning are higher murder rates than ours in other countries that also have strong gun control laws (Brazil, Russia) -- or lower murder rates in some countries, such as Israel, where guns are more widely available than in the United States.
Guns are not the problem. People are the problem. Weapons matter primarily when the wrong people have them and the right people don't. It is the imbalance in weapons that creates the danger.
This is not rocket science. We should not even have needed the studies which have shown that gun control laws don't work. What we really need to do is stop and think
