The sad part is that 100 years ago Hiram Maxim, who lived in London developed and demonstrated his machine gun in his back yard and no one thought any thing about it. Not to mention Dr. Watson carrying his unregistered, unlicensed Webley when he was going about with Holmes. It was an accepted fact that in any group of people there would be a percentage that refused to function with in the limits of society and that the rest of society needed to be able to protect itself. England had a law that if a police officer "Raised the hue and Cry" in pursuit of a criminal citizens were REQUIRED to assist him in catching the bad guy. Now self defense is basically illegal. That's liberal logic for you.
