Please explain to me how we can control guns. Like we control illicit drugs? If there is a demand there will be a supply. End of story.
I have submitted to many background checks. Thats all fine and dandy...it says I am stable and reasonable....now...no....wait, it says I can say what they want to hear. Without a history, and an honest "criminal", it will get you no where. How can you presume to say what will happen in the future, good or bad. What if I snap tomorrow...they already said I was good to go. How do you stop that with a background check? If you ban a gun you create premeditation, or force the use of a different tool.
Other societies have not controlled the guns, they have controlled the desire for citizens to own them....that is a clear and defining difference.
