Most people understand that gun control is worthless as a tool to control crime or even reduce gun accidents. The people using guns in crime are by definition not the sort to obey gun laws. Similarly, the people inclined to shoot themselves or friends while playing William Tell will find some way to off themselves, no matter what you do. The only result of gun control is to harass honest citizens exercising their rights as citizens.
The mountain of data in support of liberalized gun laws is beyond dispute. Even if you are not inclined to dig into the details, the fundamental logic is manifest. People who abide by the laws are, by definition, not the sort to break the laws. That means people who break the law are not interested in any new laws you are passing. Therefore, passing gun laws will only inconvenience those who follow the law and do nothing to stop the criminals. At best, gun laws are just a tool of the state to go after the more clever street gangs.
