First off, my country is England, you know, one of those places where you don't have hundreds of people running around firing at eachother on a daily basis. Second, observe. Even in a gun happy state like California, police records are made of every gun purchase from an authorised dealer, you need a permit to carry a concealed weapon, and all assault weapons must be registered. I'd really like to see a source for your facts, because i fail to believe that even the American government would be stupid enough to destroy gun ownership records after 24hours.
